[CMake] Problems with static jpeg library

[world at masterdevops.eu]

Hi,

thank you for your reply. I could solve the problem. The part I didn't

I've found a good summary of this topic at 
https://lists.debian.org/debian-devel/2016/05/msg00309.html
I want to share it for those, who also stumble upon this problem.
