Yes, that is correct. Unfortunately I am now out of ideas.
I found now the problem: LYX_USE_CXX11 is never set.I can test this by uncommenting this in line 15 of regex.h then the comilation works.
I applied Kornel's patch for FindCXX11Compiler.cmake and I have there set(LYX_USE_CXX11 1) set(CXX11_FLAG "") But this has obviously no effect. Kornel, what can i do here? thanks and regards Uwe
