Let's define some property on A target, why not start with includes ? Let's build an application that uses ModernCMake library. Thanks again, I appreciate all your help! The default install step builds the install target of the external project Default: Nothing; Advanced. Source Install Prerequisites. The executable can be anything, so it could be a test program, e.g. Chocolatey is trusted by businesses to manage software deployments. Credits from Pablo Arias from the article "It's time to do CMake Right". The CMAKE_INSTALL_PREFIX cache variable tells CMake where to install your project. The repository is splitted into two differents parts: The library contains some dummy C++ code (that's not the point) to show how to make a library in a modern-cmake-way. So in the case of -DCMAKE_INSTALL_PREFIX:PATH=install, the installation directory will be relative to the build directory of the external project, which is build\extern-prefix\src\extern-build\. In order to be used by the find_package command, the DepTargets.cmake file should be included in the DepConfig.cmake file used by the find_package. The target_include_directories uses a complicated generator expression to avoid certain issues with circular dependencies. In Unix: Just execute make install or sudo make install if you did set the install prefix to /usr/* (6) Notice that a file SuiteSparseConfig.cmake should be located in your install directory. C/C++ libraries are pulled from external repositories, built, and statically-linked into libOpenColorIO. A quick look to the ./sampleExec shared libraries (ldd or otools), and you will see that both ModernCMake::A & B are linked. If instead you used the “out-of-tree” build type, you will need to install the built files by using the command cmake--install. Expected CMake executable at /usr/local/android-sdk/cmake/bin/cmake. So… based on that, I concluded that the next step was to create findDep.cmake in Main. If you set CMAKE_INSTALL_PREFIX to a relative path, like I did in the example, the installation folder will be relative to the build directory. Here's the basic structure of the project: The concept here is to build two libraries (libA & libB), libA depends on std::thread "library" (an imported target provided by CMake), and libB depends on libA. In particular, the system will be able to handle multiple installed versions and multiple configurations. I did some experimentation and it seems like that’s about all I needed actually; I was able to remove all of the target imports and exports and the packaging still worked. The interesting part are the generated cmake files. in the build directory of the plugin (similarly to what you have done with SOFA in the last section). I still suspect it is likely due to the dependency on the staging dir, but I can't remove it because then it errors because the directory doesn't exist. I try here to explain a few basic concepts that you should keep in mind when creating a library with CMake using the ModernCMake library as an example. The OS-machine.tar.gz files are gziped tar files of the install tree. Here are the simple steps to download, configure, compile, and install CMake on a … Includes directory may be different between build and install, so with generators I can tell to the target where to find headers. …. I'm compiling CMake now to test it, and I'll answer if … AND THAT'S IT, we don't want to link with additionnal library or includes 1000 directories, because exported targets are transitives (they forwards theirs needed requirements) and also exports the public headers. Let’s say you have your main project called Main that have a dependency on a library called Dep. Chocolatey integrates w/SCCM, Puppet, Chef, etc. One may alternatively download and build CMake from source. Install from Android Studio under File/Settings/Appearance & Behavior/System Settings/Android SDK/SDK Tools/CMake. Here I use what cmake called generator-expressions. Here we just told CMake to install our library and to register the target in the export jsonutils-export. The binary from the external project ends up in the directory build\extern-prefix\src\extern-build\install and still does not get included in the NSIS installer or the CPack directory in the main project. I'll show how to install the latest CMake version on Linux. I am not sure if this was the right thing to do, because intuitively to me it seems like Dep should provide this find script since only it should know its targets, right? To install a .sh file, run it with /bin/sh and follow the directions. Find your required external libraries, here I will use std::thread and CMake made a nice imported target to use it. There are pre-compiled binaries available on the Download page for Windows as MSI packages and ZIP files. As a result if you write an application or a library that use for example ModernCMake::B, it will automaticaly forward the link to ModernCMake::A and therefore the link to Threads::Threads ! The cmake executable is the command-line interface of the cross-platform buildsystem generator CMake. In your case, you want to find a lib that you compiled yourself, so you want to use the Config mode. This makes the testing process quite a slow endeavor. I think this makes a lot of sense, but I actually attempted this before putting CPack in Main. Tutorial about doing CMake Right (Official repo is now https://github.com/IRCAD-IHU/modern-cmake-tutorial), Tutorial/Example to deal with modern cmake. (Programs you create yourself and use CMake to generate build scripts for don't automatically support this, but I believe CMake does.) The suite of CMake tools were created by Kitware in response to the need for a powerful, cross-platform build environment for open-source projects such as ITK and VTK. By default it points to C:/Program Files (x86)/${PROJECT_NAME}. There is no structure. Using a custom install dir should fix the problem. This error message is very confusing because if(TARGET extern_binary) is true, and the target clearly has properties. Let's take a look in the install folder of ModernCMake, you can see that config files are installed in path/to/the/install/dir/lib/cmake/ModernCMake/ , you will see 4 files: The most important part are in the ModernCMakeTargets.cmake. $ cpack -C "Release" -G "STGZ;TGZ" The command is executed in the build directory. Let me know if there’s something I missed here. I have went ahead and converted my example to use the SuperBuild format. The is just a placeholder to what you give in the INSTALL_DIR option in the ExternalProject_Add command. After using a package manager, the next recommended way to use Corrosion is to install it as a package using CMake. This command only does something if the enable_testing() has already been run, otherwise it does nothing. This adds a test to the current directory that will be run by CTest. R2020b involved a large replacement of the ROS functionality in MATLAB. They are prefixed by the version of CMake. The example shows you how to made thoses dependencies transitives. Select the Debug configuration by setting CMAKE_BUILD_TYPE to Debug. CMake provide a function to generate a basic configVersion file. Is it just for programs that don’t need to be packaged? Rust_COMPILER:STRING - Path to an actual rustc. The only prerequisite of ignition-cmake is cmake. To install CMake via the command line is straightforward. CMake Install. The install command copies the generated .lib/.a, .dylib/.dll and all headers into the appropriate directories determined by the CMAKE_INSTALL_PREFIX, usually set to /usr/local on Mac and Linux and C:/Program Files on Windows. Conslusion. Here’s an excerpt from Main’s CMakeLists.txt that handles the external project Every CMake project that is meant to be used by other CMake projects should “export” its targets. CMake will ask you to set the ModernCMake_DIR. Enough preambles. I’m assuming that you just included the configure_file step because this is a standard step in the “Superbuild template” and to show me somewhere that I can expand on it later, is that correct? We will use the following commands to generate this file: where the DepConfig.cmake.in file content is as follows: Now that we have written/generated all the necessary files, the superbuild needs to be adjusted in order to allow the Main project to find its dependency. I am looking to have CMake clone and build a git repository as an ExternalProject, then package in the resulting binary files with the main project. Introduction¶. My guess is that it uses the philosophy of *nix systems: If the dependence is a static lib, you don’t need to package it, and if it is a shared lib, you need to package it on its own…, Powered by Discourse, best viewed with JavaScript enabled, https://cmake.org/pipermail/cmake/2011-May/044344.html, The main project does run the external project’s install step, but it can’t find the directory containing the built binary file and I need to specify that somewhere, If this isn’t possible, what is the least intrusive way that I can use, forwarding the dependencies build locations using the, adding an explicit dependency to the corresponding external projects using the. I have went ahead and made the changes you suggested, but unfortunately it still does not work, here are my questions: I assumed that both of these should go in Dep’s CMakeLists.txt, I put them there, more or less as you had them, but since the external project only has a single executable, the first command ended up looking more like this: It seems like the output after configuration matches the contents of DepConfig.cmake.in exactly, there’s no @ variables in DepConfig.cmake.in, and it’s using the @ONLY parameter. If I try this I end up with nothing in the package and the cpack folder is completely empty. By default it points to C:/Program Files (x86)/${PROJECT_NAME}. INSTALL(DIRECTORY DESTINATION directory) - nothing happends SET(CPACK_GENERATOR "ZIP") INCLUDE(CPack) ----- but i cannot stick the empty directory inside, only way around i found was creating a dummy file. If you want to automate the building of Dep for the developers of Main, you should use the Superbuild pattern. Let me know if you have any more ideas. To build it launch (from a build directory): $ cmake ../../../src/modern_cmake/executable -G Ninja -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/Path/to/a/install/directory/. Note that CMake generates ${PROJECT_NAME}, ${PROJECT_VERSION}. CMake is a family of tools designed to build, test and package software. Currently, the latest version is 3.2.2, the following instructions based on this version. We’ve shown how RetDec uses modern CMake to build, install, and expose its components. But there is nothing like peace of mind brought by the knowledge that somewhere out there, there is a powerful server tirelessly compiling all the possible configurations of your project. Please avoid globbing expression, it is much more readable if all necessary files are written in the add_library. CMake is an open-source and cross-platform build system. Throughout this post, I’ll be assuming a 3.x CMake version and an already existing CMake project. CMake is an open-source, cross-platform family of tools designed to build, test and package software. When the library is installed you will see some additionnal files installed by CMAKE in your/install/dir/lib/cmake/ModernCMake. With this find script, it locates extern_binary, but this binary is still not packaged when I build the PACKAGE project in Main. In this post, I will show you how to install your library so that it can be used easily by other projects. Now that your project builds and installs correctly, you should be able to package it by doing include(CPack) in the Main project. The correct include pathshave been set up by cmake. Usually, Module mode is used when you try to search for a system library or utility, and Config mode when you try to search a library that you built. Install rules specified by calls to the install() command within a source directory are executed in order during installation. Other methods will do nothing # They can be combined $ conan build . The CMAKE_INSTALL_PREFIX cache variable tells CMake where to install your project. You can see that each of our targets exports their own includes dirs and link libraries. Starting with the 4.5 release, it is possible to configure and compile the source code with it. Install rules in subdirectories added by calls to the add_subdirectory() command are interleaved with those in the parent directory to run in the order declared (see policy CMP0082). No. You can also provide more complex mechanism with PRIVATE headers, etc... Last but not the least is the export of our target. The external project’s install rules are not part of the main project’s install rules, so if anything from the external project should be installed as part of the main build, these need to be specified in the main build as additional install() commands. It will be required for your programs to correctly build and link against SuiteSparse. The documentation for ExternalProject mentions this: Install Step Options: Not to mention that functions like include_directories work at the directory level and apply to all entities defined in scope. I tried it again just now and I got the same result. If you look into the main CMakeLists.txt you will see. Does this look familiar to you? The executable file does not appear to be copied to anywhere the main project would know about, either. Let me know if you have any other suggestions, thanks. I think CMake forbid the installation of IMPORTED targets, that is why you have this error. They will not refer to the sources, but directly to the binaries that have been installed. These targets won’t be the original targets, but what we call IMPORTED targets. This repository contains samples to deals with modern cmake (imported targets, etc...). All you need to dois install the required dependencies first. I am not really sure why we can’t install imported targets. Exports are therefore just a set of targets that can be exported and installed. The flow of control of this operation is… surprising to say the least, I don’t think I would have figured this out without your help! One of the biggest selling points is its ability to manage native builds on MS Windows. You should therefore check this URL and adjust the file name accordingly. … Setting up SDL2 with CMake under Ubuntu Linux is pretty easy. I am on Ubuntu 16.04. Is there any other way to to do this? after that run ninja, and magic of cmake should happend. Each project should be self managed, installing its own targets. I’m not sure why the install commands from the external project can’t “transfer” over to the main project. Though, I don’t quite understand how the Main project is made aware of Dep's targets. CMake uses the CPack module to generate the configuration files CPackConfig.cmake and CPackSourceConfig.cmake. Hit Configure again. My find script looks like this, to be honest I’m not 100% sure what I’m supposed to do here, it kind of seems like I’m redefining the targets of Dep (which doesn’t seem like a very clean way to do it). I think CMake supports sudo make uninstall run from the same place you ran sudo make install. Here we just told CMake to install our library and to register the target in the export file. The tar file distributions can be untared in any directory. The idea behind the superbuild is to create a specific CMake project that will. There is no transparency. CMake is a cross-platform, open-source build system. If set to a rustup proxy, it will be replaced by a path to an actual rustc. You should not, I guess. Then we can go ahead and install the export that we defined above: The above Synopsis lists various actions the tool can perform as described in sections below.. To build a software project with CMake, Generate a Project Buildsystem.Optionally use cmake to Build a Project, Install a Project or just run the corresponding build tool (e.g. CMake is used to control the software compilation process using simple platform and compiler independent configuration files, and generate native makefiles and workspaces that can be used in the compiler environment of your choice.. In CMake, installed targets are registered to exports using the EXPORT argument. command ${cmake_command} -e touch ${staging_dir} to the custom command to update the directory timestamp (which worked fine), but the problem persisted. You will need to set it to the install/dir/of/ModernCMake/lib/cmake/ModernCMake, so that cmake find the config files, remember ? The Dep_DIR variable should point to the folder containing the DepConfig.cmake file, which gives: With all of the above, your project should install correctly, and build using the superbuild pattern. We create a gzipped tarball and a self-extracting archive with the command. I suppose I’ll also put my github repositories here too, in case it helps anyone else: If it’s not possible to install using imported projects, what is the purpose of importing targets? What about the order of linking? Just out of curiosity I tried forwarding this on to the external project thinking that maybe it would magically cause the external project’s install statements to be treated the same as install statements in the main project, but that didn’t seem to happen. Based on these configuration files, CPack produces its output. There are several ways to install CMake, depending on your platform.. Windows. For example, here, I install the external project in the install subdirectory of the binary directory: Usually, I want the dependencies to be installed alongside the main project, so I just forward the CMAKE_INSTALL_PREFIX: I notice that CMAKE_INSTALL_PREFIX is “C:/Program Files (x86)/Tutorial” in the main project, which doesn’t make much sense to me. Yes, you need to take care about that yourself. This time there should be nothing in red and the Generate button will be available. https://github.com/IRCAD-IHU/modern-cmake-tutorial, https://pabloariasal.github.io/2018/02/19/its-time-to-do-cmake-right/, https://gist.github.com/mbinna/c61dbb39bca0e4fb7d1f73b0d66a4fd1, https://rix0r.nl/blog/2015/08/13/cmake-guide/, https://www.youtube.com/watch?v=y7ndUhdQuU8&feature=youtu.be. In a sample project I have created an External Project that also uses CMake as its install system, it has an install command that looks like this: The ExternalProject_Add command in my main project’s script looks like this: Unfortunately the executable file from the External Project is not getting packaged in by CPack. Exports are therefore just a set of targets that can be exported and installed. CMake (cross-platform make) is a relatively new build system that is gaining in popularity. In CMake, installed targets are registered to exports using the EXPORT argument. So you don't have any excuses to not provide Config Files. CMake is an excellent cross-platform build tool for automatically generating Unix Makefiles, Windows NMake Makefiles, Microsoft Visual Studio® Solution projects or Apple Xcode® projects for MacOS.It has its own domain specific language and various modules for most commonly used libraries and software frameworks. After that you can build sampleExec to link against ModernCMake library in a modern-way. You are right, this code should be part of Dep main CMakeLists.txt. As you have found, it supports rosgenmsg natively in the toolbox (no support package required), but does have new dependencies on Python and CMake. $ cmake path/to/modern_cmake/src/library -G Ninja -DCMAKE_BUILD_TYPE=[Release or Debug] -DBUILD_SHARED_LIBS=ON -DCMAKE_INSTALL_PREFIX=/path/to/install/dir. Yeah no suprise, but if we look at the CMakeLists.txt of sampleExec you will that. If you want a Debug build, build it first. You are just blindly throwing stuff into a pot of include directories and compiler flags. I found this: https://cmake.org/pipermail/cmake/2011-May/044344.html, To resume, the CPACK_INSTALL_CMAKE_PROJECTS variable is a list containing, for each project you want to install, its. Toinclude SDL2 headers you just use #include "SDL.h". I have two ExternalProject_Add statements similar to yours now, the superbuild concept makes a lot more sense now, thanks. But usually, projects want to expose some configuration variables to the installation, so a configure step is needed. This library installs the Google official CMake binary, and also tricks Gradle into believing that you installed CMake the official way through the SDK Manager. Description¶. The find_package command have two different modes: Module and Config. Installing CMake on Windows 윈도우에 씨메이크 설치하기 https://ubinos.org Automated Installation¶. I am hoping there’s a builtin command I missed that would work seamlessly on all platforms (Windows, Mac, and Linux). -c -b # run cmake.configure() + cmake.build(), but not cmake.install() nor cmake.test If nothing is … The most common use of CMake is to build projects that are … First time using a Linux system. Once done, export the installation path of SofaPython3 inside the SP3_INSTALL … While the two first blocks are only setting some filenames or paths, the interesting part is the end. The OS-machine.tar.Z files are compressed tar files of the install tree. We want to do this in a nice way so that users will only to call somehting like this: and to link the desired target to their library/application. Unfortunately, when I try that, it fails with the error message: install TARGETS given target “extern_binary” which does not exist. In you case, this is not really needed. This tutorial assume that you already know how to write a CMakeLists.txt. Yep, looking at the source, the install of imported targets is actively forbidden in CMake 3.17, (1), CMake 3.13.5 (which is what I’m using) does something… else (2)? After that I tried adding an install command to Main’s CMakeLists.txt, to install the imported target. I did not get any errors from CMake from the, I was able to verify that the target was getting imported into the Main project using, I didn’t really expect this to work because the generated SUPERBUILD_EXTERNTargets.cmake file is clearly using, I didn’t have much success with this route either; I tried using both, The documentation also says that it’s rarely needed to extract the location out of an imported target, but I don’t see a good example of how to have Main use this imported target…. You can also launch sampleExec to see that we use both libraries: You signed in with another tab or window. For Linux nothing else is required. How to force CMake install / CPack to create an empty directory. This files are realy the basis of doing cmake right, while when writting find_package(myPackage)CMake will first looking for myPackageConfig.cmake ! If you need A library, you only want to link against A. CMake is used to control the software compilation process using simple platform and compiler independent configuration files, and generate native makefiles and workspaces that can be used in the compiler environment of your choice. Just don’t. And this isn’t even the real problem, what do you do with transitive dependencies? Imported Targets. It seems to be more complicated than I thought. Please read comments in each CMakeLists.txt for detailled informations about each instruction. Otherwise set CMAKE_BUILD_TYPE to RelWithDebInfo. We only ask cmake to find ModernCMake::B and to link ModernCMake::B to sampleExec. Unfortunately there still seems to be something missing here. I think that maybe the packaging step should go to the superbuild script. This is the first installment of How to CMake Good. (this does not include my experimentation with attempting to have Main add it as a PROGRAM). Listed dependencies with a preceeding * can be automatically installed at build time using the OCIO_INSTALL_EXT_PACKAGES option in your cmake command (requires an internet connection). sudo apt-get install cmake When cmake is already installed: sudo apt-get upgrade Compile it yourself. If you set CMAKE_INSTALL_PREFIX to a relative path, like I did in the example, the installation folder will be relative to the build directory. I think this would probably work but it seems a bit hokey. This is the default. On Ubuntu systems, apt-get can be used to install ignition-cmake: $ sudo apt install libignition-cmake<#>-dev Be sure to replace <#> with a number value, such as 1 or 2, depending on which version you need. the executable folder contain a CMakeLists.txt and a main.cpp. I still have a couple more questions though, At first I tried just include(CPack) in my “root” build script that contains both of these ExternalProject_Add statements, it seemed promising at first, but the NSIS installer and the CPack directory contained nothing at all after I ran package from the root visual studio solution, The next thing I tried was having the Main external project be responsible for packaging, I included CPack in that project’s CMakeLists.txt instead. Nothing fancy here, the project is defined by a NAME a VERSION and the main LANGUAGES. Don’t. This is wrong in so many dimensions. But since B needs A and thanks to our nice exported targets cmake find everyting, that's transitivity baby ! Before going into the Packaging step, you need to have a fully working superbuild, so let’s focus on that first. I have no idea what this error message is really trying to say.
