[Buildroot] [PATCH 2/2] python-meson: new package

Sat Jun 4 13:34:03 UTC 2016

This new package provides the Meson Build System, an open source build
system meant to be both extremely fast, and as user friendly as
possible.

More precisely, Meson creates configuration files for the Ninja build
system.

The host variant is also provided, which, besides building Meson,
generates a cross-compilation configuration file:
'$(HOST_DIR)/etc/meson/cross-compilation.conf'.

To be able to perform checks when cross-compiling, the host variant
depends on host-qemu.

To cross-compile a Meson-based project for the target, its package
should:

 - depend on host-python-meson
 - invoke the host variant of Meson with the
   *--cross-file=$(HOST_DIR)/etc/meson/cross-compilation.conf* option.
 - invoke host variant of Ninja to perform the actual build.
