oh, this is definitely more than what should be necessary.

Why do you have to set all the suffixes and prefixes ?
This should go into Platforms/QNX.cmake.

Manually setting CMAKE_AR etc. should also not be necessary, this should also 
go into QNX.cmake or QNX-qcc.cmake or somewhere like this.

The specific build flags are your choice.
