While you're in here it'd be good to move this include to after PROJECT since the GNUInstallDirs module uses platform information initialized by PROJECT to determine the default lib directory:

CMake Warning (dev) at /opt/cmake/3.27.7/share/cmake-3.27/Modules/GNUInstallDirs.cmake:243 (message):
  Unable to determine default CMAKE_INSTALL_LIBDIR directory because no
  target architecture is known.  Please enable at least one language before
  including GNUInstallDirs.
Call Stack (most recent call first):
  CMakeLists.txt:3 (INCLUDE)
This warning is for project developers.  Use -Wno-dev to suppress it.
