Why latest Debian's Sid (Sid, which is after Debian Buster 10.0) testing repositories doesn't contain .pc file for pkg-config?
Result of dpkg -L freeglut3-dev:

Note that in freeglut's repository there is freeglut.pc.in file and is included in CMakeLists.txt.
I know that there are some threads about this issue, but they don't refer to any Linux distribution.
