Clang builds on the LLVM optimizer and code generator, allowing it to provide high-quality optimization and code generation support for many targets. This was trivial to set up in Gentoo. The whole quote is: Meson supports the standard CC and CXX environment variables for changing the default compiler, and CFLAGS, CXXFLAGS, and LDFLAGS for setting options to the compiler and linker.
