This is my latest toolchain file version:
http://quickgit.kde.org/?p=scratch%2Flpapp%2Fwikireader.git&a=blob&h=5c6c4dbda324a8285f99115c3de7d45e441d47ca&hb=f296afed1993d7c28edd5f9adcfd41465667d823&f=frontends%2Fblackberry%2Fcmake%2FToolchain-QNX-8.0.0.cmake
At least, it is clear now what I should achieve, but the CMAKE_C(XX)_FLAGS*
do not seem to work as I would expect them to.
