It's a bit of a crazy way...

qt5-webengine has python27 in BUILD_DEPENDS, but not in RUN_DEPENDS.
Prepare such a package by downloading it from somewhere.
# If you want to download it from the official, the URL should be as follows, but I can't find it directly right now :)
# And this is the package for 12.x amd64.
# https://pkg.freebsd.org/FreeBSD:12:amd64/latest/All/qt5-webengine-5.15.2_2.txz

Install the package you got that way, ignoring its dependencies. The command is as follows.
pkg add -A -M ./qt5-webengine-5.15.2_2.txz

Then use the following command to check for missing dependencies and build it in the usual way.
pkg check -d -n qt5-webengine


Best regards.
