Porting OpenCV to QNX 

OpenCV, a widely used computer vision library, also required several modifications to function correctly on QNX.

CMake configuration for QNX

In the CMakeLists.txt file, the following code sets the Python installation path when building for QNX:

if(${CMAKE_SYSTEM_NAME} MATCHES QNX)
  set(OPENCV_PYTHON_INSTALL_PATH ${QNX_PYTHON_INSTALL_PATH})
endif()

This change ensures that the Python bindings for OpenCV are correctly configured and installed when building for QNX.

System header compatibility

In the modules/core/src/system.cpp file, the inclusion of system headers accounts for QNX-specific definitions:

#if defined(__QNX__)
  #include <sys/elf.h>
  #include <sys/auxv.h>
  using Elf64_auxv_t = auxv64_t;
  constexpr decltype(auto) AT_HWCAP = NT_GNU_HWCAP;
#else
  #include <elf.h>
#endif

These modifications ensure that the correct headers and definitions are used when compiling for QNX, preventing potential compilation errors. Find a detailed issue log here.
