Perhaps something else is setting OPENGL_INCLUDE_DIR prior to hitting
that block...? cc'ing the CMake list to see if anyone else has had CMake
problems with Cygwin/OpenGL...
FIND_PATH results are cached, so you won't know the original source of
OPENGL_INCLUDE_DIR unless you configure from scratch (start with an
empty binary dir)...
Add this to see if it's set before you hit that block:
MESSAGE(STATUS "OPENGL_INCLUDE_DIR='${OPENGL_INCLUDE_DIR}'")
If it's empty, then it sounds like it might be a bug... If it's set then
we look for somebody else setting it before getting here...
HTH,

Quoting David Cole <[EMAIL PROTECTED]>:
I could be wrong, but I'm pretty sure WIN32 is *always* defined on
Windows CMake, even under cygwin. You are using the cygwin cmake,
right? ("which cmake" from your cygwin prompt should report
"/usr/bin/cmake" as opposed to the one installed in program files...)
Yes, it's /usr/bin/cmake, and yes (using your "print it" debugging
technique) I verified that both WIN32 and CYGWIN are defined.
So scratch my theory...
According to the message statements I put into FindOpenGL.cmake, this
bit is indeed being executed
IF (WIN32)
IF (CYGWIN)
FIND_PATH(OPENGL_INCLUDE_DIR GL/gl.h
/usr/include
/usr/include/w32api
/usr/X11R6/include
)
I put MESSAGE(STATUS "FindOpenGL: include dir is ${OPENGL_INCLUDE_DIR}")
right after this and it says /usr/X11R6/include was found. However,
I do have /usr/include/w32api/GL/gl.h
[EMAIL PROTECTED] -l /usr/include/w32api/GL/gl.h
-rwxr-x---+ 1 srobbins Users 79874 Apr 14 07:56
/usr/include/w32api/GL/gl.h
so I have no clue why FIND_PATH() doesn't pick it up.
Yours in puzzlement,
