How to remove -DDEFAULT_RMW_IMPLEMENTATION=rmw_fastrtps_cpp from CPPFLAGS?

Why is

-DDEFAULT_RMW_IMPLEMENTATION=rmw_fastrtps_cpp

added to my CPPFLAGS even after I

export RMW_IMPLEMENTATION=rmw_cyclonedds_cpp

like https://docs.ros.org/en/foxy/Installation/DDS-Implementations/Working-with-Eclipse-CycloneDDS.html#switch-to-rmw-cyclonedds tells me to?

Host in question is running Foxy on Ubuntu Focal.
