I am sorry that this should be an recurring question. But I wasn't able to find any working solution after hours of search.
What I tried is as follows: /root/CMakeLists.txt set(CMAKE_CXX_COMPILER mpic++) set(CMAKE_C_COMPILER mpicc) project (taesoo_cmu) add_subdirectory(BaseLib) add_subdirectory(MainLib) add_subdirectory(MainLib/luabind-0.7) add_subdirectory(OgreFltk) ----------------------- in the OgreFltk directory, project (OgreFltk) and add_executable (OgreFltk ...) is defined. cmake . make VERBOSE=true revealed that I am still using c++ instead of mpic++. What should I change? Thanks.
