No but the Wiki http://www.cmake.org/Wiki/CMake
is a good start.

Moreover I advise you to read (even fast read) the
documentation "man cmake" or "http://www.cmake.org/HTML/Documentation.html
".

"standalone" startup time  with CMake is from 1 to 3 days
where you find yourself "lost".

After that period you keep getting things work as you want
faster and faster.

Seems you need to link with OpenGL.
Try add the following to

FIND_PACKAGE(OpenGL)
IF (OPENGL_FOUND)
  MESSAGE(STATUS "Looking for OpenGL - found : ${OPENGL_gl_LIBRARY}")
  GET_FILENAME_COMPONENT(GLPATH ${OPENGL_gl_LIBRARY} PATH)
  LINK_DIRECTORIES(${GLPATH})
ELSE (OPENGL_FOUND)
  MESSAGE(STATUS "Looking for OpenGL - not found")
ENDIF (OPENGL_FOUND)

ADD GL library

TARGET_LINK_LIBRARIES(${CurrentExe} ${OPENGL_gl_LIBRARY})

That code seemed to work for OpenGL,  thanks.

I am still getting some unresolved symbols, but none that have anything to
do with OpenGL:

/usr/bin/ld: Undefined symbols:
_ClipRect
_GetPort
_GetWindowPort
_SetPort
_SetRect
_GetWindowPortBounds
_AECountItems
_AECreateDesc
_AEDisposeDesc
_AEGetNthPtr
_AEGetParamDesc

searching for these terms on google always show me something that is Apple
specific, and I found one old mailing list post about how CMake thinks I'm
not compiling on a OS X anymore, and that I need to trick it into changing
the compiler. I checked out my CMakeCache.txt file in my project directory,
and I found these lines:

//C compiler.
CMAKE_C_COMPILER:FILEPATH=/usr/bin/gcc

//CXX compiler.
CMAKE_CXX_COMPILER:FILEPATH=/usr/bin/c++

I'm not sure if the CXX compiler is correct, or if it should be g++. I tried
changing it there but it didn't go anything. Any ideas?
thanks for the help,
dave
