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
It's not a bug in Wireshark, it's a bug in your build, IMO.
If your plugin calls C math functions, the "math library" is an external linkage requirement; some platforms have a separate "math library", some don't.  M_LIBRARIES should be set as necessary by the CMake module for libm.
And if my plugin calls requires libfoozbar that's an automatic 
libwireshark dependency then? Or doesn't call C math functions, why 
should my plugin be force to link with libm? Point is any library is 
already available to plugins.
