I am new to Qt, I created a GUI application in Qt and everything was fine, until I changed the Build directory from Projects section in QtCreator. Now I get many linker errors which I am clueless on how to resolve them.
I tried reverting back to the previous build folder, but it failed again. I do clean the project and do a rebuild each time, yet nothing works. Here is a list of those linker errors I'm getting:

How can I find out what the cause is. ?
I found a way to get rid of this nerve-racking problem.
First try running qmake, if it didn't help, just delete the .pro.user file which resides next to your .pro file. After that try to open your project, Just press reconfigure and you are good to go.
In case you got QMake error (qmake is missing or something like that) run qmake first, then you are good to go.
