FindGLPK
--------
This module determines the GLPK library of the system.
IMPORTED Targets
^^^^^^^^^^^^^^^^
This module defines :prop_tgt:`IMPORTED` target ``GLPK::GLPK``, if
GLPK has been found.
Result Variables
^^^^^^^^^^^^^^^^
This module defines the following variables:
::
``GLPK_FOUND``
True if ``GLPK`` found.
``GLPK_INCLUDE_DIRS``
Where to find glpk.h, etc.
``GLPK_LIBRARIES``
List of libraries for using ``glpk``.
Hints
^^^^^
A user may set ``GLPK_ROOT`` environment to a GLPK installation root to tell this
module where to look.
