Hmm, the only difference I did was unzip into a different
subdir and call
   export QT_SELECT=qt5
   cmake -DCMAKE_INSTALL_PREFIX=/opt/sigil ../Source/

I retried now with your incatations with the same effect.

What kind of information would help? I checked my installation
now and there is only one package from experimental: libqt5-dev
which might be related. But this is only a meta-package.

I have some other pakcages from experimenatal, but unrelated
(libpoppler, vala) and home-brewn stuff (latex mostly, wpa,
unison, .. nothing related to qt5 or compilation).
