Summary of key changes

Lib  Key Change  Reason 
nghttp2 Updated CMake configuration  To correctly build the test suite for QNX. 
Modified header file inclusions  To include QNX-specific headers and handle system differences. 
QNX buildfile changes 

Configure QNX toolchain, disable unnecessary features. 

OpenCV Updated CMake configuration  To set the Python installation path for QNX. 
Modified system header inclusions  To handle QNX-specific system headers and definitions. 
QNX buildfiles 

Select essential modules, configure cross-build. 

By addressing these platform-specific differences, both nghttp2 and OpenCV can successfully be ported to QNX, enabling their use in embedded and real-time applications, where QNX is the operating system of choice.
