I guess we may leave a commit message like:

In order to directly import erofsfuse with a new static library.

Maybe only leave this line here?
AM_CONDITIONAL([ENABLE_STATIC_FUSE], [test "x${enable_static_fuse}" = "xyes"])

Maybe the following way also works?

lib_LIBRARIES = liberofsfuse.a
liberofsfuse_a_CFLAGS = ...
liberofsfuse_a_CFLAGS += -Dmain=erofsfuse_main ${libfuse2_CFLAGS} ${libfuse3_CFLAGS} ${libselinux_CFLAGS}
liberofsfuse_la_LIBADD =

I guess we don't need -static + la IMHO...
