Build fail - MainWindow.ui not found

[TheLittleSub]

Dear merek-cel,
After cloning your repo, I tried to build the project but an error occurred:

mingw32-make[1]: *** No rule to make target '../example/MainWindow.ui', needed by 'ui_MainWindow.h'.  Stop.
mingw32-make: *** [Makefile:38: debug] Error 2

The process "C:\Qt\Tools\mingw730_64\bin\mingw32-make.exe" exited with code 2.
Error while building/deploying project example1 (kit: Desktop Qt 5.12.12 MinGW 64-bit) When executing step "Make"

Could you please tell me if you are aware of this problem?

Thank you!
