Package names are distribution-specific, but it's common to use a -dev
or -devel suffix for packages which are only required when compiling.

It's entirely possible that the nVidia OpenGL package doesn't have a
corresponding development package. In which case, you probably need to
make the symlink manually, e.g.:

	ln -s libGL.so.1.2 /usr/lib/libGL.so

Essentially libGL.so must exist in one of the system library
directories (e.g. /usr/lib) and must point (directly or indirectly) at
the actual OpenGL library (which will normally have a version number
after the ".so").
