A workaround for Paraview was posted on the mailing list, and based on it I was able to create a fix for VTK. The Paraview fix is:<br><br><a href="http://public.kitware.com/pipermail/paraview/2007-October/006141.html">http://public.kitware.com/pipermail/paraview/2007-October/006141.html</a><br><br><br>The fix for VTK is as follow (assuming something like that has not been posted already):<br><br>Modify the Top Level CmakeLists.txt file in the IF(VTK_USE_RENDERING) section as follow:<br><br>insert the lines:<br>IF ( OSX_LEOPARD_OPENGL_FIX )<br> SET (CMAKE_EXE_LINKER_FLAGS "-Wl,-dylib_file,/System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/libGL.dylib:/System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/libGL.dylib")<br> SET (CMAKE_SHARED_LINKER_FLAGS "-Wl,-dylib_file,/System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/libGL.dylib:/System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/libGL.dylib")<br>ENDIF ( OSX_LEOPARD_OPENGL_FIX )<br><br>and just before the IF(VTK_USE_RENDERING) section, insert the line:<br>OPTION(OSX_LEOPARD_OPENGL_FIX "Adds Linker arguments needed to correctly select the X11 OpenGL Library" TRUE)<br><br>so that the end result is:<br><br>#-----------------------------------------------------------------------------<br># Configure OpenGL support.<br><br>OPTION(OSX_LEOPARD_OPENGL_FIX "Adds Linker arguments needed to correctly select the X11 OpenGL Library" TRUE)<br>IF(VTK_USE_RENDERING)<br># At the moment CMake's FindOpenGL considers OpenGL should be found<br># in the framework version on OSX.
