Qt5 module

The Qt5 module provides tools to automatically deal with the various tools and steps required for Qt. The module has one method.

preprocess

This method takes the following keyword arguments:

• moc_headers, moc_sources, ui_files, qresources, which define the files that require preprocessing with moc, uic and rcc
• include_directories, the directories to add to header search path for moc (optional)
• moc_extra_arguments, any additional arguments to moc (optional). Available since v0.44.0.

It returns an opaque object that should be passed to a main build target.

A simple example would look like this:

qt5 = import('qt5')
qt5_dep = dependency('qt5', modules: ['Core', 'Gui'])
inc = include_directories('includes')
moc_files = qt5.preprocess(moc_headers : 'myclass.h',
                           moc_extra_arguments: ['-DMAKES_MY_MOC_HEADER_COMPILE'],
                           include_directories: inc)
executable('myprog', 'main.cpp', 'myclass.cpp', moc_files,
           include_directories: inc,
           dependencies : qt5_dep)

The 'modules' argument is used to include Qt modules in the project. See the Qt documentation for the list of modules.
