Add options for precompiled headers build faild.

If I want to speed up building projects, I need to add options for precompiled headers.

so,I modified my project configuration.

but,I got a build error.

qmake\qtvars_plugin_import.cpp(14,1): fatal error C1010: unexpected end of file encountered while looking for precompiled headers. Did you forget to add "include" pch.h "to the source.

The project in the attachment may reproduce this problem. You must use static QT to reproduce it.
