c - CMake错误找不到openmp_c不合适的Mac版本

Question

我运行了以下命令，但发现错误。知道如何解决吗？运行带有集成 GPU（Intel Graphics HD 4000）和专用 GPU（NVidia Geforce GT 650M）的 Mac OSX 10.12.6 (Sierra)。英特尔处理器。

cmake .. -DCMAKE_CXX_FLAGS=-stdlib=libc++ -DCMAKE_OBJCXX_FLAGS=-stdlib=libc++ -DOpenMP_C_INCLUDE_DIR=/opt/local/include/libomp -DOpenMP_CXX_INCLUDE_DIR=/opt/local/include/libomp -DCMAKE_LIBRARY_PATH=/opt/local/lib/libomp -DBINARY_PACKAGE_BUILD=ON -DRAWSPEED_ENABLE_LTO=ON -DBUILD_CURVE_TOOLS=ON -DBUILD_NOISE_TOOLS=ON -DDONT_USE_INTERNAL_LUA=OFF

输出：
