Review changes made for Issue #53 CMake

I've made all the CMakeList files the project needs. I managed to get the project to build, compile and install. However, when I try to run the qmlscene ui/main.qml, it can't seem to find the directories where the plugins are installed. Could you have a look?
Yes, this is exactly the mechanism I used to add new files. It's unfortunately all done manually, so any news files in html or ui directories need to be changed in these files. I'll add the missing resources.
