Maybe, but (a) I have no idea how the .pc files are created, so I would have to
use sed or perl to change the files after installation, and (b) I am not sure
that would be enough (see below):

Not sure what you mean with that...? These are only build time requirements,
used only by the preprocessor...?

Wireshark uses the latter form. But Qt itself uses the former. Hence:

Since both uses occur, we'd have to do both.
Anyway, for the time being, I am working around it in my package like this:
export PKG_CONFIG_PATH=$QT_PATH/lib/pkgconfig:$PKG_CONFIG_PATH
export PATH="$QT_PATH/bin:$PATH"
QT_LIBS="-F$QT_PATH/lib"
QT_CPPFLAGS="-F$QT_PATH/lib"
for fw in QtCore QtGui QtWidgets QtPrintSupport QtMacExtras QtMultimedia ; do
QT_LIBS="$QT_LIBS -framework $fw"
QT_CPPFLAGS="$QT_CPPFLAGS -I$QT_PATH/lib/$fw.framework/Headers"
done
export LIBS="$LIBS $QT_LIBS"
export CPPFLAGS="$CPPFLAGS $QT_CPPFLAGS"
It seems Gnuplot is doing something similar.
Cheers,
Max
