I got the answer from CLion blog and it works and here it goes.

To provide CMake compiler paths, go to Settings | Build, Execution, Deployment | CMake and pass as CMake options:

-D CMAKE_C_COMPILER=-D CMAKE_CXX_COMPILER=

In case CMake fails to find some path to clang libs, etc. you can also set there environment variables:

CC=/usr/bin/clangCXX=/usr/bin/clang++

ubuntu下设置clion是使用clang和clang++
