I don't think any configure.ac in minisip supports auto detections of 
macros during the bootstrap. They all require that the needed m4-files 
are available.

We could copy libzrtpcpp/m4/libzrtpcpp.m4 into libminisip/m4, and add it 
as EXTRA_DIST, but it shouldn't be added to aclocal_DATA and installed. 
That will remove the dependency of libzrtpcpp during bootstrap of 
libminisip.
