I had a similar issue a month or so ago, what helped was a clean cloning
of LyX source. Now even that doesn't work, and it's been like that for 2
or 3 weeks. It might be due to newest Qt libraries that came with Fedora
23, not sure. Can you read anything from this backtrace?
(...after installing 3GB of various debuginfos)

here's the run_cmake.sh I used

Same thing even if I go back in time, to some 9/2015 commits I know worked.
Doesn't matter if I set CXX11 to ON or OFF.
