Bug in Devuan (pkgconf)

What is:

$ pkgconf --libs --cflags gl
-lGL 
$ pkgconf --libs --cflags GL
Package GL was not found in the pkg-config search path.
Perhaps you should add the directory containing `GL.pc'
to the PKG_CONFIG_PATH environment variable
Package 'GL', required by 'virtual:world', not found 

What should be:

$ pkgconf --libs --cflags gl
-I/usr/include/GL -lGL 
$ pkgconf --libs --cflags GL
-I/usr/include/GL -lGL

Otherwise, you may get errors like this:

dependency GL found: NO
OpenGL Spectrum Analyzer: false

A workaround might be obvious, if you do not suffer from dementia.

What might be needed is "/usr/include/" in a sort of 'virtual:path' in the so-called 'virtual:world'. This might be an esoteric problem.
In any case, a simple workaround fixed the problem. Now it looks like this:

dependency GL version: 1.2 found: YES
OpenGL Spectrum Analyzer: true 

However, opengl.pc might also be wrong:

$ pkgconf --libs --cflags opengl
-lOpenGL 

It seems that "gtk+-3.0" was already fixed:

$ pkgconf --libs --cflags gtk+-3.0
