Have you considered splitting your library into a fortran-only library and a
C-only library?  Autotools tries to support mixing fortran- and C-compiled
objects in the same library (using the AC_F77_LIBRARY_LDFLAGS macro and the
resulting FLIBS), but we could never get that to work reliably on all
platforms for PLplot.  Thus, we ended up splitting our libraries into
fortran-only and C-only when we were still building with autotools, and we
have continued that approach now we have migrated to cmake.  We didn't have
to do anything special to get this approach to work. Just use the
appropriate ADD_LIBRARY command for each library, and use
TARGET_LINK_LIBRARIES to establish the dependencies between them, and the
result seems to build fine on all platforms.
