Why freeglut3-dev doesn't provide .pc file for pkg-config?

Question

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.

This post is more appropriate for Debian bugtracker, isn't it? – Chowchow

Someone already posted it on Debian bugtracker. – Inamorata

BTW: Lack of .pc file for freeglut isn't big problem, because CMake has GLUT's CMake module (which is preferred). You can check it running cmake --help-module-list | grep -i glut. – Inamorata

Lack of .pc file is actually a problem if you build project without CMake. – Chowchow
