configure doesn't autodetect paths, it only confirms that any paths
specified by the user work. If a path needs to be passed onto the
compiler or linker, the user has to supply it.

I take it that -framework is limited to the linker? I.e. the compiler
still needs explicit -I flags?

Oops; trying to use "make" sytnax instead of shell syntax:

It's still meaningful if OpenGL is disabled.
