cmake unnecessarily copies osvr libraries about osvr-rendermanager

[russell-taylor]

This lets us get a working install when the library is built from source and there is not an installed OSVR Core library. This is how I build, and other developers do the same. Is the extra copy causing a problem? If not, then I think it is more general to leave it in.

It's not really a problem, they'll just be overwritten with themselves. I just saw it when making an Archlinux AUR package for render manager: with a simple make install the package wouldn't install because those 4 libraries were already in /usr/lib. Well, it's trivial to remove them from the package when building (or to remove the line from CmakeLists.txt with sed).

Okay, then I'll go ahead and close the issue. Thanks for letting us know about it.

Ideally this would be enabled on Windows only, and/or be behind an option(), but if you can work around it in packaging, that works for me :)
