Qt DLL's needed to publish emulator?

[pascal_meheut]

Did you had a look a wp34s's QtGui Makefile?
It is based on Qt 4.8 and copy some dll for windows, uses a Qt provided tool for OSX and relies on Qt being already installed on Linux.
For Qt5, the process is slightly different as you need to copy "platform" files too but basic idea is the same.

I do not know of any installer but they may exists. But when adding the Qt emulators to the wp34s project, I wanted to limit external dependencies to the maximum. Hence the choice of doing everything by hand.
