It looks like it should take this header from the source package, not from whatever is installed into /usr/local. In the top-level CMakeLists.txt, there is this fragment: include_directories(.) include_directories(include) include_directories(src) which indicates to CMake it should add -I flags for each of those directories. However, it seems -I/usr/local/include is placed earlier in the arguments of the actual clang++ invocations: /usr/bin/clang++ -DFreeOCL_EXPORTS -O2 -pipe -I/usr/local/include -fno-strict-aliasing -I/usr/local/include -stdlib=libc++ -std=c++0x -DFREEOCL_USE_CXX0X -DFREEOCL_ARCH_amd64 -O3 -ffast-math -fPIC -I/usr/work/share/dim/ports/devel/freeocl/work/FreeOCL-0.3.6-Source/. -I/usr/work/share/dim/ports/devel/freeocl/work/FreeOCL-0.3.6-Source/include -I/usr/work/share/dim/ports/devel/freeocl/work/FreeOCL-0.3.6-Source/src -o CMakeFiles/FreeOCL.dir/image.cpp.o -c /usr/work/share/dim/ports/devel/freeocl/work/FreeOCL-0.3.6-Source/src/image.cpp So it will take /usr/local/include/CL/cl.h before the cl.h under ${WRKSRC}. Now, as to how we can convince CMake to put the -I/usr/local/include at the end... Maybe we should just patch the CMakeLists.txt, but that is a rather ugly solution. :)
