Installation failure: Unknown pkg-config option "--with-path=XXX" and undeclared glfw functions during mmlgui make

[Spicy-Lost-Soul]

I'm running on VM running the latest version of Debian running in VMWare Workstation Pro.

I'd had to install libvgm manually.

Via apt I'd had to install libglfw3(-dev), g++, cmake, zlib and pkg-config.

When I try to install mmlgui via make I've gotten the following error for every g++ file running pkg-config:

Unknown option --with-path=/usr/local/lib/pkgconfig

Even with the following variable set: export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig

I'd end up getting glfw-related function errors later in the make process:

It appears like freedesktop pkg-config doesn't support that command line option. I use this version, which does not have that issue. I'm not sure what the best fix would be, as normally (at least from my experience), libvgm installs itself in usr/local, an unusual place, making that option necessary.

The GLFW error I suspect is due to the library being outdated. Please try the latest version

I also had to delete the --with-path options to get mmlgui to build on macOS.
