[CMake] Including an external object file (.o) into static shared library using MS Visual Studio generator

[Chatterjee, Shash]

Hi David,

I truly appreciate your willingness to help, and your prompt response.  Thanks a bunch!

I just installed 2.8.4 and tried again.  As far as I can tell, the behavior did not change (I deleted the CMake-2.8.3 generated build directory, as well as uninstalling CMake-2.8.3).  I still see the <ClInstall> element for the .o file, and it does not get included in the library.

Thanks,
Shash

This was a known bug, and has been fixed in CMake 2.8.4.

See here for details if you want:

Upgrade to CMake 2.8.4 and try again. Should work....


Cheers,
David
