Sorry. I had forgotten your attempt.

The good thing with your attempt is that it splits the output into two files 
(The part that need to be included and the part that do not).

 Another problem is that you have to moc before you compile any file which
 needs the moc generated headers.

That's a small build system issue.

  You install the output from moc.

 Yes. That is a build system issue which is not difficult to solve.

 And it's only if the said QObject is in a header file which also needs to be
 installed, and that you do not rely on extern template.

Are you recommending that people use this feature only for non-public classes?

I'm saying that it can be used first with non-public classes before we change 
the build system to install the needed generated files.

 Hi All,

 I am currently trying to link my software component
 libs(propreitary) with Qt Libs to form a DLL which will further be used by
 my application.
 In doing so I am facing linker issues. I did check if the symbols are
 present in the libs and Yes they are present in Libs, but still its unable
 to link.
 I am currently using Qt 4.8.4 on Windows using Visual Studio command
 prompt.
 The linker command on make is as follows.
