Take contrib/ltree as an example, in Makefile, there are some lines:

ifdef USE_PGXS
PG_CONFIG = pg_config
PGXS := $(shell $(PG_CONFIG) --pgxs)
include $(PGXS)
else
subdir = contrib/ltree
top_builddir = ../..
include $(top_builddir)/src/Makefile.global
include $(top_srcdir)/contrib/contrib-global.mk
endif

I am taking these as the reason that extension can build outside of postgres
source code, but I can't find an equivalent in meson.build.
