qgroundcontrol building error

[sanomu]

:-1: error: LNK1181: 'obj\QGCMapEngine.obj' Input file can not be opened.

What should I do? T_T

@sanomu You should provide whole build log so others can see what the actual error is.
And give us more information about your environment: Qt version, compiler used, OS, QtCreator or Visual Studio...

@sanomu you may also want to ask for support with the QGroundControl application developers as well...
