Here I use what cmake called generator-expressions. Starting with the 4.5 release, it is possible to configure and compile the source code with it. Now that your project builds and installs correctly, you should be able to package it by doing include(CPack) in the Main project. 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. As you have found, it supports rosgenmsg natively in the toolbox (no support package required), but does have new dependencies on Python and CMake. You should therefore check this URL and adjust the file name accordingly. 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/. (this does not include my experimentation with attempting to have Main add it as a PROGRAM). The idea behind the superbuild is to create a specific CMake project that will. I think this would probably work but it seems a bit hokey. The target_include_directories uses a complicated generator expression to avoid certain issues with circular dependencies. The CMAKE_INSTALL_PREFIX cache variable tells CMake where to install your project. R2020b involved a large replacement of the ROS functionality in MATLAB. Let me know if you have any more ideas. You can also launch sampleExec to see that we use both libraries: You signed in with another tab or window. By default it points to C:/Program Files (x86)/${PROJECT_NAME}. This time there should be nothing in red and the Generate button will be available. Then we can go ahead and install the export that we defined above: 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! Description¶. The find_package command have two different modes: Module and Config. 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. If set to a rustup proxy, it will be replaced by a path to an actual rustc. 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. 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. 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. 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? 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…. If you look into the main CMakeLists.txt you will see. Just don’t. The example shows you how to made thoses dependencies transitives. Default: Nothing; Advanced. Install from Android Studio under File/Settings/Appearance & Behavior/System Settings/Android SDK/SDK Tools/CMake. This command generates installation rules for a project. 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. Exports are therefore just a set of targets that can be exported and installed. Let's define some property on A target, why not start with includes ? This seems like the right way to do it and I think I’ve seen other superbuilds do this. This command only does something if the enable_testing() has already been run, otherwise it does nothing. Toinclude SDL2 headers you just use #include "SDL.h". For Linux nothing else is required. One may alternatively download and build CMake from source. You can see that each of our targets exports their own includes dirs and link libraries. 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\. After that I tried adding an install command to Main’s CMakeLists.txt, to install the imported target. (Programs you create yourself and use CMake to generate build scripts for don't automatically support this, but I believe CMake does.) By default it points to C:/Program Files (x86)/${PROJECT_NAME}. 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. Automated Installation¶. What about the order of linking? Here we just told CMake to install our library and to register the target in the export file. The is just a placeholder to what you give in the INSTALL_DIR option in the ExternalProject_Add command. 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. CMake will ask you to set the ModernCMake_DIR. Yes, you need to take care about that yourself. There are several ways to install CMake, depending on your platform.. Windows. This repository contains samples to deals with modern cmake (imported targets, etc...). I'll show how to install the latest CMake version on Linux. You are right, this code should be part of Dep main CMakeLists.txt. 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? 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. 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. 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. 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. This makes the testing process quite a slow endeavor. What happen if you include CPack there ? The only prerequisite of ignition-cmake is cmake. When the library is installed you will see some additionnal files installed by CMAKE in your/install/dir/lib/cmake/ModernCMake. First time using a Linux system. It will be required for your programs to correctly build and link against SuiteSparse. Though, I don’t quite understand how the Main project is made aware of Dep's targets. With this find script, it locates extern_binary, but this binary is still not packaged when I build the PACKAGE project in Main. So you don't have any excuses to not provide Config Files. Please read comments in each CMakeLists.txt for detailled informations about each instruction. The executable can be anything, so it could be a test program, e.g. I’m not sure why the install commands from the external project can’t “transfer” over to the main project. Here are the simple steps to download, configure, compile, and install CMake on a … After that you can build sampleExec to link against ModernCMake library in a modern-way. These targets won’t be the original targets, but what we call IMPORTED targets. 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. 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 ! You will need to set it to the install/dir/of/ModernCMake/lib/cmake/ModernCMake, so that cmake find the config files, remember ? Thanks again, I appreciate all your help! Setting up SDL2 with CMake under Ubuntu Linux is pretty easy. There is no structure. They are prefixed by the version of CMake. Based on these configuration files, CPack produces its output. 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. Unfortunately there still seems to be something missing here. This is wrong in so many dimensions. Includes directory may be different between build and install, so with generators I can tell to the target where to find headers. Chocolatey is software management automation for Windows that wraps installers, executables, zips, and scripts into compiled packages. Credits from Pablo Arias from the article "It's time to do CMake Right". Chocolatey is trusted by businesses to manage software deployments. CMake Install. Please avoid globbing expression, it is much more readable if all necessary files are written in the add_library. 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? The tar file distributions can be untared in any directory. I think this makes a lot of sense, but I actually attempted this before putting CPack in Main. I think that’s because the SuperBuild CMakeLists.txt doesn’t have anything except ExternalProject_Add commands: If it is necessary to put install commands in this, then, well, it seems to me that we’d end up in the exact same situation that Main is in, where we can’t install imported targets. Expected CMake executable at /usr/local/android-sdk/cmake/bin/cmake. The most common use of CMake is to build projects that are … 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)? To install a .sh file, run it with /bin/sh and follow the directions. The OS-machine.tar.Z files are compressed tar files of the install tree. CMake uses the CPack module to generate the configuration files CPackConfig.cmake and CPackSourceConfig.cmake. If you need A library, you only want to link against A. Note that CMake generates ${PROJECT_NAME}, ${PROJECT_VERSION}. In CMake, installed targets are registered to exports using the EXPORT argument. I tried it again just now and I got the same result. I took a wild guess and assumed that maybe from the perspective of the Main project, extern_binary is no longer a TARGET and is actually a PROGRAM. Chocolatey integrates w/SCCM, Puppet, Chef, etc. 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. I have two ExternalProject_Add statements similar to yours now, the superbuild concept makes a lot more sense now, thanks. Hit Configure again. We only ask cmake to find ModernCMake::B and to link ModernCMake::B to sampleExec. Before going into the Packaging step, you need to have a fully working superbuild, so let’s focus on that first. 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. Don’t. 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.
