[Mesa-dev] [PATCH] meson: Add script to use VERSION file for getting version

[Dylan Baker]

Quoting Dylan Baker (2017-11-01 11:58:16)
> Meson has up until this point set it's version in the root meson.build
> script. While there are other build systems them creates "one more
> thing" to duplicate between meson and every other build system, this
> script is a simple "read, strip, print" sort of deal to allow meson to
> read the VERSION file.
> 
> I chose to implement this in python since python is portable, and to
> keep the meson.build script clean. This is also complicated by the fact
> that the project() call *must* be the first non-comment,non-blank in the
> toplevel meson.build script.
