freeglut build status - 3.4.0 builds

[shawnlaffan]

Updating to freeglut 3.4.0 and applying the patches used by the MSYS2 project gets freeglut working.

Notes below are in advance of a PR.

Patches: https://github.com/msys2/MINGW-packages/tree/0c8da415d1531ccef1530931b867a4c2a5cbf1de/mingw-w64-freeglut

The diff below also includes an update to modernise the cmake invocation to run in a clean dir, and corrects the pkgconfig path when it is updated (s{lib/lib/pkgconfig}{lib/pkgconfig} )
