CMake: Fix pkgconfig calls when cross-compiling
When cross-compiling with CMake, before this patch pkgconfig calls would
find libraries which are part of the host system and not the target
system.
The current approach used is based of the discussion present in
https://gitlab.kitware.com/cmake/cmake/-/merge_requests/4478, and should
be considered a temporary solution until the issue is properly addressed
in upstream CMake.
