| Once SIP is built and installed into the virtualenv, PyQt5 can be handled. By default the configuration script will enable all PyQt5 sub-modules for which necessary pre-requisite Qt5 libraries and headers are available. The ''--disable'' flag can be used to prevent any unnecessary sub-modules from being built. | Once SIP is built and installed into the virtualenv, PyQt5 can be handled.
