QT5-DECLARATIVE FreeBSD compile issues

[Tobias C. Berner]

Unfortunately we cannot really support FreeBSD 11.x anymore for Qt --
with the switch to Qt5 5.15
we had to drop support for it, due to its outdated OpenSSL version in
base, which does not work with
qt5-networks requirements.
As qt5-declarative also depends on qt5-network, this is completely
untested, and may likely also fail
with the compiler version present in FreeBSD 11.x.

My recommendation would be to update to a more current version
FreeBSD, like for example 12.x or
the soon to be released 13.x.
