Since the project is using qmake as it's build system, you could
try:

find . -name "*.pro" -o -name "*.pri" -print0 | \
    xargs -0 grep -A 3 -E "QT.*="

to find all the lines of the type

QT += core gui widgets

and the such. Then you could go through those and see if there is
a "libqt5XXX5-dev" package (replace XXX with the module) available.
Some things are in qtbase5-dev directly (such as the 3 examples I
have above) though.

It could also be that some modules of Qt aren't packaged yet at
all. For example - and I may be mistaken about that - I don't
believe there's a libqt5datavisualization5-dev for that module in
Debian yet.
