[CMake] PKG_CHECK_MODULES cppunit

[Michael Bowerman]

Philip,

Thanks!  I actaully was trying that way.  But, changed it.  Stupid me.

I copied the linked script as-is and it worked.  It found the lib64 path,
with no problem.

The problem I was having before (that made me try the PKG_CONFIG) was caused
by not having the ENABLE_TESTING() macro in the top level CMakeLists.txt.
So, make test did nothing.

Thanks again for the fast help.
