For now (today) qt5 build fails with the following error message:

In file included from /var/tmp/portage/app-text/coolreader3-9999-r2/work/coolreader3-9999/cr3qt/src/bookmarklistdlg.h:4:0,

Similiar build failure known for dev-db/tora. Suggested workaround:

update: sed'ing -ggdb3 to -ggdb3 -fPIC in CMakeLists.txt fixed the problem.

And right solution:

// although, it will be nicer, if your buildsystem inherited system's C{,XX}FLAGS (that set in the environment)
