I commented out lines 89-159 in the CMakeLists.txt file because I only needed the librtlsdr.h, .so, .a and dll file.

Any ideas on how to get the rest of it to compile?

Probably the same dependency conflict issue as here https://github.com/rtlsdrblog/rtl-sdr-blog/issues/25. Can you try the fix I mentioned there?
