-"""
-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 = sorted(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
