QtCreator doesn't not allow selection of the QNX C compiler (qcc)

QNX OS is popular in the Automotive sector. CMake also popular in the Automotive sector.

When Qt Creator is used to compile a CMake project, CMake will fail because one cannot select a C compiler for QNX.

Qt Creator has for compilers only QCC, which is mapped to C++.

QNX 6.6.0 has QCC as the C++ compiler wrapper, while qcc is the C compiler wrapper.
QNX 7.0.0 has q++ as the C++ compiler wrapper, while qcc is the C compiler wrapper.

One can use the generic C and C++ compiler options, but if you do that then the C++ code parser gets confused and doesn't map standard headers.

Also you can modify the CMAKE_C_COMPILER:STRING=%

in the CMake Kit Configuration and put there the path to qcc, but it would be better if the compiler selector would just know about qcc.
