In the library’s root CMakeLists.txt, it can be detected by comparing CMAKE_CURRENT_SOURCE_DIR with CMAKE_SOURCE_DIR: they’re only the same if it is the real root of the source tree.Īs such, we only define test targets, when this is not the case: It is therefore a good idea to prevent that by only exposing those helper targets when not used as a subdirectory.
#CMAKE INCLUDE DIRECTORIES VISUAL STUDIO DOWNLOAD#
However, this includes targets that are not useful for downstream consumers like unit tests, documentation builders, and so on.Ĭrucially, this includes the dependencies of those targets – when using a library, I don’t want CMake to download that libraries testing framework! This makes all targets of the project available in the parent, so you can link against them and use them. If a project is used via FetchContent, CMake will automatically call add_subdirectory(). Let’s look at the library side of things for the remainder of the post. Very simple and straightforward, refer to CMake’s documentation for more details. This will automatically download the project and make the targets available so you can link against them and have them built as necessary.įetchContent_Declare ( lexy URL ) FetchContent_MakeAvailable ( lexy ) # Link against lexy's targets now.

Hide developer targets like tests, provide a zip archive that contains only the source files relevant downstream, and use GitHub actions to create it automatically.įetchContent is a CMake module that makes downloading or “fetching” dependencies really trivial.Īll you need is to let CMake know where the sources are with a call to FetchContent_Declare() and then include them as a subproject with FetchContent_MakeAvailable().
If you’re a library writer, there are ways you can structure your CMake project to improve the experience for end users that use FetchContent:
#CMAKE INCLUDE DIRECTORIES VISUAL STUDIO CODE#
If all you need is to get the source code of a library, include in your CMake project, and have it compiled from source with the rest of your project, CMake’s FetchContent module can do it for you. Id really appreciate some guidance with this.If you’re working on an executable project in C++, as opposed to a C++ library, using a package manager to get your dependencies might be overkill: I also tried Properties > VC++ Directories > Include Directories but that didn't work at all.
That seemed to work but I wanted to know if that is the correct/only way to do it? My solution was to simply add the include directory of my project in Properties > C/C++ > General > Add additional include directories. This means that if I want to include a header from my code I have to write "././include/some header.h" rather than include and that is annoying. One of those changes is to switch the project to "show all files" so that the project directory reflects what it looks like on disk rather than the Visual Studio default and I have the executable being compiled and built inside a bin folder outside of the source but still within the project. I have been tinkering around with Visual Studio so that I can get it to work as closely as I would like as possible.

I recently switch to Windows for C++ development from OSX and Linux.
