[CMake] Do transitive interace includes propagate to compilation of Fortran sources?

[Zaak Beekman]

Hi,

OK, unless the answer to the question in the subject line should be "NO",
then please disregard this email. I think I was having a caching issue with
my super build setup. I'm pretty sure that transitive includes are being
correctly propagated now.

Sorry for the noise,
Zaak
