I’ve added:
PG_LDFLAGS += -L$(shell $(PG_CONFIG) --pkglibdir) -lbtree_gist

to Makefile and I get the following:

ld: library 'btree_gist' not found
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Note that I am on Mac and btree_gist.dylib is present in $(pg_config —pkglibdir)
