Ah that might be something different. It might be that grass 7.4 still tries to use the old 
proj_api.h. I'm not completely sure of the effect of building GDAL 3 with  
ACCEPT_USE_OF_DEPRECATED_PROJ_API_H defined. I'd say, either drop the GRASS driver if 
you don't need it, or upgrade to a more recent GRASS version that can use PROJ >= 5 API
