libpng required dependency #17

Closed szellmann closed 9 years ago

szellmann commented 9 years ago

On a system where libpng is not installed, cmake will configure and generate successfully, but linking will fail later. For someone w/o knowledge of the covise source code, I find this type of error kind of hard to track down, especially because the error messages don't relate to png. Not sure what's the best way to fix this..
