macos - cmake libclang 与 macos 上的自制 llvm

问题描述

我尝试使用带有 llvm(homebrew) 的 cquery 在 macos 上构建 cquery，但找不到某些库。

$ 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
-- Detecting CXX compile features
-- Detecting CXX compile features - done
-- Using system Clang

解决方案

根据this page，CMAKE_PREFIX_PATH用于find_*功能。
