This looks like you do not have meson correctly installed somehow, or
perhaps an unsupported version?

Looking at the location in ~/.local/bin/meson - I assume you have
installed it with pip.

Perhaps try the following:

  pip3 install meson --upgrade


Or if you are running python2:

  pip install meson --upgrade



Otherwise I would suggest you remove the build directory and try a clean
build from scratch as the simplest next step.
