pkg-meson: new infrastructure
Add a new infrastructure to ease the development of packages that use Meson as their build system. Signed-off-by: Eric Le Bihan <eric.le.bihan.dev@free.fr> [Thomas: - move global variables definition outside of the inner-meson-package macro - for consistency, remove double quote around value passed to meson in the host configure step. - minor formatting fixes.] Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com>

# Meson package infrastructure
|
||||
#
|
||||
# This file implements an infrastructure that eases development of
|
||||
# package .mk files for Meson packages. It should be used for all
|
||||
# packages that use Meson as their build system.
|
||||
#
|
||||
# See the Buildroot documentation for details on the usage of this
|
||||
# infrastructure
|
||||
#
|
||||
# In terms of implementation, this Meson infrastructure requires
|
||||
# the .mk file to only specify metadata information about the
|
||||
# package: name, version, download URL, etc.
|
||||
#
|
||||
# We still allow the package .mk file to override what the different
|
||||
# steps are doing, if needed. For example, if <PKG>_BUILD_CMDS is
|
||||
# already defined, it is used as the list of commands to perform to
|
||||
# build the package, instead of the default Meson behaviour. The
|
||||
# package can also define some post operation hooks.
|
||||
