meson, cmake: Ensure verbosity

  o cmake: The `V=1` environment variable only works when running make,
    and the `VERBOSE=1` environment also only works with make, in order
    to ensure commands are printed in the logs with either make or ninja
    we need to set -DCMAKE_VERBOSE_MAKEFILE=ON.

  o meson: In order ensure we get verbosity with ninja we need to
    pass it the `-v` command line option.
