Currently, when building, the cmake example in projects/CMake gives this warning, with CMake 3.30.2
CMake Warning (dev) at /usr/share/cmake/Modules/FetchContent.cmake:1953 (message):
Calling FetchContent_Populate(raylib) is deprecated, call
FetchContent_MakeAvailable(raylib) instead. Policy CMP0169 can be set to
OLD to allow FetchContent_Populate(raylib) to be called directly for now,
but the ability to call it with declared details will be removed completely
in a future version.
Call Stack (most recent call first):
CMakeLists.txt:20 (FetchContent_Populate)
This warning is for project developers. Use -Wno-dev to suppress it.
Changing FetchContent_Populate to FetchContent_MakeAvailable didn't cause any issues I could observe when building. I'm not sure why it wasn't like that to begin with.
