        And how exactly does this prevent me from doing:
baz: baz.c
        gcc -o baz baz.c -L/usr/lib/foo/amd64-linux -lfoo

        No, I do not need to do any such thing. I can just inspect the
 files shipped, and adjust accordingly.  It is _convenient_ to use
 pkg-config, but I am not forced to use it.  We have been linking
 libraries for _decades_ before pkg-config was invented

        So, if you want to use the convenience of pkg-config; build
 depend on it.
