I think something similar was on this list a couple of days ago, it's
a missing include (that wasn't neccessary before Qt5.15), there's 21
similar bugs filed already c.f.[1].
A quick and easy fix for this problem should be this:
1. create a file /etc/portage/env/missing-qpainterpath-flags and insert
this line:
====
CXXFLAGS="${CXXFLAGS} -include QPainterPath"
====
2. add the line
====
=media-sound/cadence-0.9.0-r4 missing-qpainterpath-flags
====
to /etc/portage/package.env (or /e/p/package.env/qpainterpath.env or
some such if you've "directoryfied" your package.env (can you?) ;)
[add more lines for specific package versions and revs for the same
problem, see [1] for candidates]
Yes, that is *quite an ugly hack*, but could be handy while stuff get's
patched to work with that specific change of Qt5.15...
FWIW: that includes that QPainterPath header in _all_ C++ sources, but
what the hey, compilers are so good today, that they throw away
anything unused, so it should not matter. It'll slow down the compile
a bit...
Once e.g. media-sound/cadence is fixed and revbumped/versionbumped,
delete that line from package.env.
It works here for a quick:

HTH,
-dnh, tending to be very pragmatic in cases like this ;)
