Q: What to do to avoid “warning: #warning _FORTIFY_SOURCE requires compiling with optimization (-O) [-Wcpp]” when compiling r2inference & gst-inference?

Edit r2inference/build/build.ninja or gst-inference/build/build.ninja for which library you choose to build. Add -O flag After -D_FORTIFY_SOURCE=2 for c_COMPILER rule (r²inference only has this) and cpp_COMPILER rule.
