"""
This tool helps with finding Qt5 tools and libraries,
and also provides syntactic sugar for using Qt5 tools.

The following snippet illustrates the tool usage::

	def options(opt):
		opt.load('compiler_cxx qt5')

	def configure(conf):
		conf.load('compiler_cxx qt5')

	def build(bld):
		bld(
			features = 'qt5 cxx cxxprogram',
			uselib   = 'QT5CORE QT5GUI QT5OPENGL QT5SVG',
			source   = 'main.cpp textures.qrc aboutDialog.ui',
			target   = 'window',
		)

Here, the UI description and resource files will be processed
to generate code.

Usage
=====

Load the "qt5" tool.

You also need to edit your sources accordingly:

- the normal way of doing things is to have your C++ files
  include the .moc file.
  This is regarded as the best practice (and provides much faster
  compilations).
  It also implies that the include paths have beenset properly.

- to have the include paths added automatically, use the following::

     from waflib.TaskGen import feature, before_method, after_method
     @feature('cxx')
     @after_method('process_source')
     @before_method('apply_incpaths')
     def add_includes_paths(self):
        incs = set(self.to_list(getattr(self, 'includes', '')))
        for x in self.compiled_tasks:
            incs.add(x.inputs[0].parent.path_from(self.path))
        self.includes = list(incs)

Note: another tool provides Qt processing that does not require
.moc includes, see 'playground/slow_qt/'.

A few options (--qt{dir,bin,...}) and environment variables
(QT5_{ROOT,DIR,MOC,UIC,XCOMPILE}) allow finer tuning of the tool,
tool path selection, etc; please read the source for more info.

The detection uses pkg-config on Linux by default. To force static library detection use:
QT5_XCOMPILE=1 QT5_FORCE_STATIC=1 waf configure
