[Samba] Building v4.15 with glusterfs VFS module, still possible?

[Jaap van Wingerden]

I've been trying to build v4.15 from source on ubuntu 20.04, since i need
gluster support. According to the documentation (
https://www.samba.org/samba/docs/current/man-html/vfs_glusterfs.8.html) it
should still be available. But compiling with --enable-glusterfs builds no
glusterfs.so.
I tried modifying source3/modules/wscript_build to hard code glusterfs to
enabled, but compilation fails looking for glusterfs/api/glfs.h . I even
tried downloading the gluster source (v9) and linking that to the
apropriate folder, but then compilation fails with errors about too many
arguments.

So this begs the question, is it possible at all to build the latest
release with gluster support?
