OK.  I've cleaned out all CMake cache files using "rm -rf CMake*".

The FindOpenGL.cmake file now looks like this:

IF (WIN32)
   MESSAGE(STATUS "FindOpenGL: WIN32 is defined...")

     MESSAGE(STATUS "FindOpenGL: CYGWIN is defined...")




And here is the output:

-- FindOpenGL: WIN32 is defined...
-- FindOpenGL: CYGWIN is defined...
-- OPENGL_INCLUDE_DIR='/usr/X11R6/include'

I don't get it.  Is there a way to have CMake verbosely explain its  
decision process in the FIND_PATH() statement?
