The incompatibilities you refer to are the result of differences in different
"vendors" C++ formats, not in the differences between library formats.
Actually a static .a and .lib have the same format.  But the former
restriction overshadows the latter non-issue.  You'll need to wrap your
library in C-callable interfaces if you really want to get this to work.
Perhaps the very recently update SWIG library will be helpful for you?
