Qwt ( http://qwt.sf.net ) offers a qch file and is available for quite 
some time. So you could check, what is common practice among distro 
packagers.

F.e. on my box ( OpenSusSE 12.2 ) it is simply not part of qwt6-devel-
doc. But the OpenSuSE package maintainer seems in general not being aware 
of these Qt specific files as the installation of the feature files is 
also broken.

But the rest of the docs can be found below /usr/share/doc/packages/qwt6-
devel-doc and IMO this is where I would expect to find qwt.qch as well.

Maybe other distros can give you a better hint.

To me one of the most error prone things is loading 3rd party plugins to 
the creator. This has mostly to do with binary incompatibilities between 
the libraries used for development and the one used by the Creator 
( Assistant is less bad as being built together with Qt libs ) , but the 
fact, that plugins are loaded "automatically" from some directories is 
part of the problem.

Coming from having experienced maximal user frustration with this 
approach I wouldn't recommend to establish such an automatism.
