I have no idea what this error message is really trying to say. As you have found, it supports rosgenmsg natively in the toolbox (no support package required), but does have new dependencies on Python and CMake. The find_package command have two different modes: Module and Config. 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. A quick look to the ./sampleExec shared libraries (ldd or otools), and you will see that both ModernCMake::A & B are linked. This tutorial assume that you already know how to write a CMakeLists.txt. 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). 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/. The cmake executable is the command-line interface of the cross-platform buildsystem generator CMake. The example shows you how to made thoses dependencies transitives. 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. CMake will ask you to set the ModernCMake_DIR. CMake (cross-platform make) is a relatively new build system that is gaining in popularity. Using a custom install dir should fix the problem. The external projectâs install rules are not part of the main projectâs 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. 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 didnât really expect this to work because the generated SUPERBUILD_EXTERNTargets.cmake file is clearly using, I didnât have much success with this route either; I tried using both, The documentation also says that itâs rarely needed to extract the location out of an imported target, but I donât see a good example of how to have Main use this imported targetâ¦. Hereâs an excerpt from Mainâs CMakeLists.txt that handles the external project I did some experimentation and it seems like thatâs about all I needed actually; I was able to remove all of the target imports and exports and the packaging still worked. You will need to set it to the install/dir/of/ModernCMake/lib/cmake/ModernCMake, so that cmake find the config files, remember ? 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 Depâs 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, thereâs no @ variables in DepConfig.cmake.in, and itâs using the @ONLY parameter. Installing CMake. Installing CMake on Windows ìëì°ì ì¨ë©ì´í¬ ì¤ì¹í기 https://ubinos.org Every CMake project that is meant to be used by other CMake projects should âexportâ its targets. In this post, I will show you how to install your library so that it can be used easily by other projects. The interesting part are the generated cmake files. I think that maybe the packaging step should go to the superbuild script. Is it just for programs that donât need to be packaged? Yes, you need to take care about that yourself. ⦠Otherwise set CMAKE_BUILD_TYPE to RelWithDebInfo. Don’t. Once done, export the installation path of SofaPython3 inside the SP3_INSTALL ⦠Before going into the Packaging step, you need to have a fully working superbuild, so letâs focus on that first. Exports are therefore just a set of targets that can be exported and installed. 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 âC:/Program Files (x86)/Tutorialâ in the main project, which doesnât make much sense to me. With this find script, it locates extern_binary, but this binary is still not packaged when I build the PACKAGE project in Main. 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\. CMake is a cross-platform, open-source build system. The idea behind the superbuild is to create a specific CMake project that will. In your case, you want to find a lib that you compiled yourself, so you want to use the Config mode. 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. This repository contains samples to deals with modern cmake (imported targets, etc...). Default: Nothing; Advanced. 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. -c -b # run cmake.configure() + cmake.build(), but not cmake.install() nor cmake.test If nothing is ⦠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? This error message is very confusing because if(TARGET extern_binary) is true, and the target clearly has properties. Here we just told CMake to install our library and to register the target in the export jsonutils-export. So⦠based on that, I concluded that the next step was to create findDep.cmake in Main. I suppose Iâll also put my github repositories here too, in case it helps anyone else: If itâs not possible to install using imported projects, what is the purpose of importing targets? By default it points to C:/Program Files (x86)/${PROJECT_NAME}. You can also provide more complex mechanism with PRIVATE headers, etc... Last but not the least is the export of our target. These targets wonât be the original targets, but what we call IMPORTED targets. After using a package manager, the next recommended way to use Corrosion is to install it as a package using CMake. 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. 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. The moment you need to deal with the dependencies of your dependencies is the moment your life needs to be reevaluated. 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. So you don't have any excuses to not provide Config Files. This time there should be nothing in red and the Generate button will be available.
