If indeed that is the problem (very likely) the decision to make these libraries PRIVATE was intentional because the only external linkage requirement that I saw was glib.
Yes this was the problem as I suspected yesterday, it just took a while to verify as I had to delete the build directory to have the cmake changes take effect. Another question
Is this bug https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=15084 also related to the cmake changes?
