Apparently latest version is 2.0.2
Please attach the entire build log to this bug report.
Created attachment 386346 [details] nomacs-1.6.2-build.log
Apparently OpenCV's pkg-config files are somewhat broken. I have opened a pull-request that tries to use OpenCV's cmake scripts first, then falls back to pkg-config stuff: https://github.com/nomacs/nomacs/pull/5
Thanks, this is fixed in the tree with 2.4.2 version bump.
