When you fail to compile software by CMake, you should directly set CMAKE_<lang>_COMPILER.
Here, <lang> means a language and is set as C for C compiler, CXX for C++ compiler, Fortran for Fortran compiler. For example, when you want to use g++, you should set the variable
by cmake -DCMAKE_CXX_COMPILER=g++.
You can also set the compile option by setting CMAKE_<lang>_FLAGS_RELEASE. For example, you can set the compile option by cmake -DCMAKE_C_FLAGS_RELEASE="-O3 -DNDEBUG -DHAVE_SSE2".
