Which package installed that /usr/local/include/CL/cl.h file? 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. :)
