![]() This makes the header file appear, but since it's just a header file and not a CMake target, there's no information on what dependencies it has or what any specializations need to link (in this case, anyone that uses foo needs to link toward stdc++fs). Don't worry, no actual binaries will be generated if you should try and build it (at least not in VS2010 and Xcode 4). ![]() The only way I can get the header file to get installed is to manually specify the include folder, which copies the whole include folder. addlibrary (HEADERONLYTARGET STATIC test1.hpp test2.hpp) settargetproperties (HEADERONLYTARGET PROPERTIES LINKERLANGUAGE CXX) This sets up your header-only project as a dummy archive target. These files must exist for the compilation to pass. The header is nowhere in build/ or install/. A few header files are generated using CMake configurefile() and included in the desired source files. I can physically SEE that the file is there and that the name should match to what Cmake is looking for. A property on a source file that indicates if the source file is a header file with no associated implementation. nothing needs to be compiled, for example, for a header-only library. This is set automatically based on the file extension and is used by CMake to determine if certain dependency information should be computed. Like everywhere in this book, just click on the command name to see the official. Using -DCMAKEFINDDEBUGMODEON only ensured me that Cmake is looking in the proper location. HEADERFILEONLY¶ Is this source file only a header file. A property on a source file that indicates if the source file is a header file with no associated implementation. Cmake finds all other FOOs without a problem. Nor does any other folder under install/foolib, and the header is not copied (or symlinked) to any dependent projects. Yes because there is no standardised build system for C++, which makes integrating non-header only libraries a pain (or at least somewhat more painful). Interestingly, FOObar is one element of a set of library files - all named FOOxxx. For example, to only install libraries, we can run the following: cmake -D COMPONENTlib -P cmakeinstall.cmake Since the Message.hpp header file was set. However, the install/foolib/lib folder contains no header files. Set_target_properties(foo PROPERTIES CXX_STANDARD 20) But then when I went to code of famous header only library like spdlog they have src folder. ![]() So after compiling the code we won't have a separate library files, and which makes it platform independent. This is because the LLVM/Clang compiler uses the MSVC APIs and libraries. ![]() In package foolib, CMakeLists.txt includes the following lines add_library(foo INTERFACE include/foolib/foo.h) On internet the header only is defined something like the definitions of the functions, macros is defined in headers itself. The former is correct - you only need to build LLVM and Clang in debug mode if. How do I do this? Making the transition from any other OS to then work on Windows has been hell.I want to make a header only cpp library for use in ROS nodes and build it with ament such that it is indexed properly and ament_target_dependency finds it and propagates transitive flags. I left off with doctest definitely installed and available but meson can't find it via cmake and pkg-config and pkgconf don't seem to be available.Īll I want to do, which I can just do on Linux and MacOS is the following series of commands: cd $PROJECT_ROOTĪll wrapped up into a nice install script like vcpkg, conan, chocolatey, apt, nix, etc. As it stands, I have ~6 different terminals (cmd, v1 Powershell, v7 Powershell, the cmd that nodejs installs and only works on it, developer cmd, developer v1 powershell), chocoloatey installed, VS Code, Visual Studio 2022 CE with Desktop C++ tooling and basically all other tooling that looks C++ related, meson, ninja, doctest via vcpkg, vkpkg, everything from, over a base Windows 10 install, a refreshed Windows 10 install, Windows 10 over the 20 major subversions, windows 11, and just more. To compile x264 with lavf you need to have ffmpeg/libav libraries installed and be in. This is with regards to the following repo. I believe that cmake is more light-weight than msys/mingw et al. option -pch-through-header that is used to either. To start, I am frustrated and have tried many, many things. In cmake-gui you can choose clangcl on optional tool set -T.
