Re: [CMake] Fwd: cmake link against Qt4's OpenGL

Look in the GLWidget source file and see if there is actually azRotationChanged(int) method available.

and try again. Also, you do actually have the MacOSX10.5.sdkavailable correct?
The link line contains all the proper OpenGL (both apple and Qt)frameworks. You just need to get past the SDK setting first.

By default it should be 10.5.sdk so I am not sure what is reallygoing wrong.
also, do the following:

make clean
make VERBOSE=1

in your build directory and lets examine the compile and link lines..

so if I use cmake 2.6.1, with the following CMakeList.txt file:

PROJECT ( COMBINED )
FIND_PACKAGE (Qt4 REQUIRED)
SET(QT_USE_QTOPENGL TRUE)
INCLUDE( ${QT_USE_FILE} )
ADD_EXECUTABLE(exe main.cpp glwidget.cpp window.cpp)
TARGET_LINK_LIBRARIES(exe ${QT_LIBRARIES})

I am able to link to Qt4's OpenGL, but I have a link error:

make

I have no idea what this error means.
