At the moment I don't have a 64bit installation, so I can't test this
myself. I'll install a system for this, because it should work.

What you can try is to take some CMake script from the Dependency Manager
CMake file. This checks if the system is Unix/Linux and 64bit, and then
sets the PIC option. I've pasted it below this message.

Also it might be convenient to disable several subdirectories, currently
everything is build, making it difficult to track and fix problems. See [1]
for more details on this. I'm working on a quick and simple fix which will
do the job for now.

I hope this helps, if not, please send a reply!
