cmake libclang與MacOS上的自制llvm

Question

我嘗試使用帶有llvm（homebrew）的cquery在macOS上構建cquery，但是找不到某些lib。

$ LDFLAGS="-L/usr/local/opt/llvm/lib"  
  CPPFLAGS="-I/usr/local/opt/llvm/include" 
  cmake -DSYSTEM_CLANG=ON  -DCMAKE_BUILD_TYPE=Release -DCMAKE_C_COMPILER=$(which clang) -DCMAKE_CXX_COMPILER=$(which clang++) .

-- The CXX compiler identification is Clang 6.0.0
-- Check for working CXX compiler: /usr/local/opt/llvm/bin/clang++
-- Check for working CXX compiler: /usr/local/opt/llvm/bin/clang++ -- works
-- Detecting CXX compiler ABI info
-- Detecting CXX compiler ABI info - done

根據此頁面 ，將CMAKE_PREFIX_PATH用於find_*函數。
