+"""
+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. The list of
+libraries to be requested to pkg-config is formulated by scanning
+in the QTLIBS directory (that can be passed via --qtlibs or by
+setting the environment variable QT5_LIBDIR otherwise is derived
+by querying qmake for QT_INSTALL_LIBS directory) for shared/static
+libraries present.
+Alternatively the list of libraries to be requested via pkg-config
+can be set using the qt5_vars attribute, ie:
+
+ conf.qt5_vars = ['Qt5Core', 'Qt5Gui', 'Qt5Widgets', 'Qt5Test'];
+
+This can speed up configuration phase if needed libraries are
+known beforehand, can improve detection on systems with a
+sparse QT5 libraries installation (ie. NIX) and can improve
+detection of some header-only Qt modules (ie. Qt5UiPlugin).
+
+To force static library detection use:
+QT5_XCOMPILE=1 QT5_FORCE_STATIC=1 waf configure
