Use -O0 alongside -ggdb3 to address compiler warning

[oleksandr-pavlyk]

Running the documentation generation workflow I encountered the following compilation warnings:

icpx: warning: Note that use of '-ggdb3' without any optimization-level \
     option will turn off most compiler optimizations similar to use of \
     '-O0' [-Wdebug-disables-optimization]

This change addressed the warning.
