GLPK has been found.

This module defines the following variables:
::
GLPK_FOUND - True if GLPK found.
Hints
^^^^^
A user may set ``GLPK_ROOT`` to a GLPK installation root to tell this
module where to look.
#]=======================================================================]
# first specifically look for the CMake version of GLPK
find_package(GLPK QUIET NO_MODULE)
# if we found the GLPK cmake package then we are done.
