-pthread is not applicable for QNX Neutrino

[oleh-derevenko]

It would be great to edit cmake files to not generate "-pthread" in CXX_FLAGS in build/tests/CMakeFiles/test_jsoncons.dir/flags.make for QNX Neutrino target. The target does not accept (and does not require) this option.

Would you consider submitting a pull request for this?

The flags are configured in jsoncons\build_files\cmake\Linux.cmake

Generally, you need to set
set(CMAKE_SYSTEM_NAME QNX)
somewhere conditionally. I'm not sure where and when exactly you do this. I'm a complete novice to cmake.

Then you can use
if(CMAKE_SYSTEM_NAME MATCHES "QNX")
to test the target.

Or probably you should use QNXNTO to name the system. "QNX" used to be used for QNX 4 OS release only. The releases starting from QNX 6 use "QNXNTO" as the name.

Alright. It looks like you need to add empty jsoncons/build_files/cmake/QNXNTO.cmake and pass -DCMAKE_SYSTEM_NAME=QNXNTO in command line
