2# QMake package infrastructure
3#
4# This file implements an infrastructure that eases development of package
5# .mk files for QMake packages. It should be used for all packages that use
6# Qmake as their build system.
7#
8# See the Buildroot documentation for details on the usage of this
9# infrastructure
10#
11# In terms of implementation, this QMake infrastructure requires the .mk file
12# to only specify metadata information about the package: name, version,
13# download URL, etc.
14#
15# We still allow the package .mk file to override what the different steps
16# are doing, if needed. For example, if <PKG>_BUILD_CMDS is already defined,
17# it is used as the list of commands to perform to build the package,
18# instead of the default QMake behaviour. The package can also define some
19# post operation hooks.
