# CMake derives a Visual Studio project GUID from the file path but can be overridden via a property
# (see https://gitlab.kitware.com/cmake/cmake/-/commit/c85367f4).  Using a non-constant GUID
# can cause problems if other projects/repos want to reference the vcxproj file,
# so we force a constant GUID here.
