Subject: meson: allow using staging python
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=41f7322853621ea14a2d057cd6322014307acc02;p=openwrt%2Fopenwrt.git

meson: allow using staging python

Introduce package flag MESON_USE_STAGING_PYTHON which allows packages
to be built with the OpenWrt-built python3/host instead of relying on the
buildhost's Python distribution.
This is useful for packages using Meson which require additional Python
modules during build.
