Building the QGC code using Qt platform

Hello everyone

I am trying to build the QGC source code using Qt tool, I have Qt version 5.12.6 , MSVC 2017, and Gstreamer version 1.16.0, but when I import the source code and try to build it, I got the following error:
:-1: error: LNK1104: cannot open file ‘QGCMapEngine.obj’

knowing that I tried to rebuild the code using Qt version 5.15.2 as specified in the QGC documentation. but I got the same error!!!

any suggestions??
Thanks in advance
