qt_add_library(STATIC) fails on QNX

qt_add_library fails to generate a library file when attempting to generate a STATIC library.  The same code works fine and builds a static library on desktop builds.  Sample application attached with build directories included showing missing library.  Here is the compiler/linker output:
