Do not allow Package Config Files (*.pc).
They are all wrong! (Assimp, ccd, fcl, flann, freeglut, glew, tinyxml2, and i assume many more)
And indistinguishable between release and debug.

There should be either:

1. an rule checker to prevent having these files
2. require them in a certain location and check the content
3. require them in a certain location and create them with a fixed pattern by vcpkg
