So shared=true will map to --enable-shared and shared=false to
--disable-shared. Did I get it right?

Well, yes, during development I don't care either. Especially on unix
platforms. For windows it's more complicated, anyway. For a build that
ships to a customer it's not that easy. :-)

This will do in my special use case. But a more general solution to
this would be nice.
