If you started with an empty build directory and set the compiler to
clang, no, you don't need to clean anything. Why should you do?

Is clang/clang++ the default compiler for FreeBSD-10? Maybe the cmake
version you are using does not know about that fact and insists on using
gcc/g++. If that's the problem, set CC and CXX environment variables (or
CMAKE_C_COMPILER and CMAKE_CXX_COMPILER cmake variables ) as I explained
on a previous message upon your *first* invocation of cmake on a clean
build directory and it should just work. If it doesn't, please show the
exact command you executed and its output.
