I'm fine with the meson version requirement. However, for some reason
the meson_version : '>0.44.0' doesn't take effect for meson_options.txt:

"""
$ rm -rf build; meson build
The Meson build system
Version: 0.42.1
Source dir: /home/jani/src/intel-gpu-tools
Build dir: /home/jani/src/intel-gpu-tools/build
Build type: native build

Meson encountered an error in file meson_options.txt, line 7, column 0:
Unknown type array.
"""

I can obviously just update meson now that I figured it out, but is
there something we could do to be more helpful for the next person
hitting this?

BR,
Jani.
