Csaba Keszegh · Csaba Keszegh · commit a190f5e660a9 · 2015-09-01T17:22:08.000+02:00
QNX cmake var should set to 1, on command line, or in a toolchain file
do not set _XOPEN_SOURCE macro when building for QNX
set SYSLIBS cmake var (see: build/config/QNX:SYSFLAG)
tested: Ubuntu 14.04, QNX 6.6.0, cmake 3.2.3
