UPD: got this working, we added "platforms" directory to a package, it contains qminimal.dll and qwindows.dll. Automation question is still actual, never the less.
We have a deployment issue: application package doesn't work on other PC. The package is made from all the libraries that were required to run app in separate folder from explorer.exe interface. The libs were taken from Qt5 installation folder (I:\Qt\Qt5.0.0\5.0.0\msvc2010\bin in that case).
We figured out, however that the only difference is Qt5Core DLL libraries. In other words, My package works on friends PC when he replaces my Qt5Core.dll with the one from his Qt installation. Those 2 dlls have different CRC, and here !http://s018.radikal.ru/i503/1304/78/1b437a7d947c.png(comparison picture)! you can see that dlls somehow store the path they were installed in. Since our paths are different, application refuses to work at all. NO ERRORS! It just swallows all the clicks and no process gets launched. This is really annoying behavior.
How does one deploy Qt5 applications now? How can I make sure my app will work on other, yet same platform PC (both win7 Ultimate sp1 x64)? Any deployment automation out there?
