There needs to be a file called libGL.so or libGL.a. libGL.so is
usually a symlink to e.g. libGL.so.1.2; the file to which the symlink
refers must exist.

If you can't see any obvious problems, check the config.log file for
any relevant error messages. It may be that one of the libraries which
libGL requires doesn't exist.
