error: LNK1181: cannot open input file 'debug\exitapp.obj'

[Anmol]

I have deleted Build folder (MSVC 2017 32bit). and i'm trying to build it again i'm getting error.
(this pic taken when it was not deleted)

i have also try to re configuring .pro file (by deleting pro file and let Qt Creator let create it again)

still i'm getting same error " error: LNK1181: cannot open input file 'debug\exitapp.obj' "

(exitapp is a QDialog which appear when user try to exit)

Please help.

@Anmol Did you rerun qmake?
Are there eny other errors before that linker error?
It looks like ExitApp.cpp was not compiled.
Can you show your pro file?
