We only ask cmake to find ModernCMake::B and to link ModernCMake::B to sampleExec. This is the default. Here we just told CMake to install our library and to register the target in the export jsonutils-export. I am on Ubuntu 16.04. The correct include pathshave been set up by cmake. 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. If you want to automate the building of Dep for the developers of Main, you should use the Superbuild pattern. It will also generate a “DepTargets.cmake” file that will contain all the targets that have been installed. The idea behind the superbuild is to create a specific CMake project that will. One may alternatively download and build CMake from source. Let’s say you have your main project called Main that have a dependency on a library called Dep. 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. 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. We’ve shown how RetDec uses modern CMake to build, install, and expose its components. Note that CMake generates ${PROJECT_NAME}, ${PROJECT_VERSION}. Description¶. There is no structure. 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? In CMake, installed targets are registered to exports using the EXPORT argument. 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.. Unfortunately, when I try that, it fails with the error message: install TARGETS given target “extern_binary” which does not exist. Though, I don’t quite understand how the Main project is made aware of Dep's targets. 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\. The CMAKE_INSTALL_PREFIX cache variable tells CMake where to install your project. Don’t. 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. 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. Chocolatey is trusted by businesses to manage software deployments. The only prerequisite of ignition-cmake is cmake. The interesting part are the generated cmake files. Default: Nothing; Advanced. The is just a placeholder to what you give in the INSTALL_DIR option in the ExternalProject_Add command. Here we just told CMake to install our library and to register the target in the export file. …. 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. How to force CMake install / CPack to create an empty directory. 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. The moment you need to deal with the dependencies of your dependencies is the moment your life needs to be reevaluated. All you need to dois install the required dependencies first. When the library is installed you will see some additionnal files installed by CMAKE in your/install/dir/lib/cmake/ModernCMake. … This repository contains samples to deals with modern cmake (imported targets, etc...). This is done like this: These install calls will make sure the Dep target is installed (its binaries, public headers, etc.). Is there any other way to to do this? CMake is a family of tools designed to build, test and package software. In your case, you want to find a lib that you compiled yourself, so you want to use the Config mode. $ cpack -C "Release" -G "STGZ;TGZ" The command is executed in the build directory. Unfortunately there still seems to be something missing here. Once done, export the installation path of SofaPython3 inside the SP3_INSTALL … The documentation for ExternalProject mentions this: Install Step Options: In particular, the system will be able to handle multiple installed versions and multiple configurations. It seems to be more complicated than I thought. 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/. 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. If you want a Debug build, build it first. the executable folder contain a CMakeLists.txt and a main.cpp. Source Install Prerequisites. By default it points to C:/Program Files (x86)/${PROJECT_NAME}. I think this makes a lot of sense, but I actually attempted this before putting CPack in Main. 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? This makes the testing process quite a slow endeavor. 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 ? 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? Setting up SDL2 with CMake under Ubuntu Linux is pretty easy. CMake will ask you to set the ModernCMake_DIR. 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. 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 instead you used the “out-of-tree” build type, you will need to install the built files by using the command cmake--install. CMake provide a function to generate a basic configVersion file. You can see that each of our targets exports their own includes dirs and link libraries. 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. This tutorial assume that you already know how to write a CMakeLists.txt. These targets won’t be the original targets, but what we call IMPORTED targets. After that I tried adding an install command to Main’s CMakeLists.txt, to install the imported target. What about the order of linking? No. The executable file does not appear to be copied to anywhere the main project would know about, either. Using a custom install dir should fix the problem. In this post, I will show you how to install your library so that it can be used easily by other projects. To install CMake via the command line is straightforward. One of the biggest selling points is its ability to manage native builds on MS Windows. 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)? CMake (cross-platform make) is a relatively new build system that is gaining in popularity. Nothing fancy here, the project is defined by a NAME a VERSION and the main LANGUAGES. Install from Android Studio under File/Settings/Appearance & Behavior/System Settings/Android SDK/SDK Tools/CMake. Here are the simple steps to download, configure, compile, and install CMake on a … Let's build an application that uses ModernCMake library. 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. A quick look to the ./sampleExec shared libraries (ldd or otools), and you will see that both ModernCMake::A & B are linked. With this find script, it locates extern_binary, but this binary is still not packaged when I build the PACKAGE project in Main. The most common use of CMake is to build projects that are … 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. 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. After using a package manager, the next recommended way to use Corrosion is to install it as a package using CMake. 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. in the build directory of the plugin (similarly to what you have done with SOFA in the last section). Chocolatey is software management automation for Windows that wraps installers, executables, zips, and scripts into compiled packages. 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. As you have found, it supports rosgenmsg natively in the toolbox (no support package required), but does have new dependencies on Python and CMake. :B and to register the target in the last section ) `` it 's time do!
