QNX7.1 compiler header file not found for Conan2.4 RESTinio Package

Hi I am trying to create a c++ Hello-world application with RESTinio api using QNX compiler.
To get RESTinio and its Dependencies I am using conan version 2.4.
This is a cross compile application where my build machine is Linux and target machine is QNX OS.

if I use gcc I can create the RESTinio app but with the QNX compiler I am getting following errors.

conan build . --build=missing
