Cutelyst is a Qt5-based web application framework. It gives you C++
for application logic and WSGI server and plugins for the webby bits.
This update adds a GRANTLEE option, enabled by default: it turns out
I hadn't enabled **any** templating in Cutelyst, which is a bit
of an annoying restriction. Grantlee is a Qt5-only templating
engine, so the additional default dependencies are fairly light.
While here, simplify some of the CMake options handling;
one thing I'm not sure about is how OPTIONs should be handled
in the ordering of pkg-plist: the Porter's Handbook section 8.1
does not offer any guidance. I've collected them at the end.
