You will need other Qt packages. It may be that those are missing. I do
not know enough about Void Linux to know whether there is some easy way
to install those. (Debian provides apt-get install build-deps or
something.) It's possible you could find out what the dependencies are
of the default package. Here on Fedora, I have:

qt5-devel-5.13.2-2.fc32.noarch
qt5-qtbase-devel-5.15.2-2.fc33.x86_64
