Wow that's not trivial by any definition of the word. With bazel and the standard bazel toolchain config, you just do:

  CC=<whatever> bazel build

You can do the same with Meson. I just added the warning, debugging, and sanitizer options in-line for clarity. The benefit (I'm not sure if Bazel has this too) is you only have to run the commands once to set up the build directories. After that, you can just use the ultra-fast ninja and almost ignore Meson completely.
