What is the correctest way to install Qt5 in Gentoo Linux?

Question

I already do following things:

# layman -a qt
# cat /etc/portage/package.accept_keywords
=x11-libs/qt-core-5.9999 **
=x11-libs/qt-network-5.9999 **
=x11-libs/qt-dbus-5.9999 **
=x11-libs/qt-declarative-5.9999 **
=x11-libs/qt-demo-5.9999 **

And what next?

Answer 1

As with any other package, you need to "emerge" the ones you want.

This seems rather easy to me, so maybe you're not quite asking what you actually mean?

Answer 2

You are looking for the package qt-core which is the main Qt5 package available in the repository/overlay.

emerge -av x11-libs/qt-core-5.9999

In addition you can select further modules. Qt5 is pretty well structured as you are now able to only install the modules which you need instead of pulling the whole bloated Qt-package.

Common used packages are for example qt-gui or qt-widgets but that depends on your requirements.
