I managed to download the sources for the pglogical extension and successful=
ly built it for my 9.6.9 instance. I then tried issuing a =E2=80=9Cmake clea=
n=E2=80=9D, then reset the PATH setting, so it could find version 10, but th=
e =E2=80=9Cmake USE_PGXS=3D1=E2=80=9D then failed with:

pglogical_output_plugin.h:20:30: fatal error: pglogical_compat.h: No such fi=
le or directory

But I do see the required file in the compat10 sub directory, so why can=E2=80=
=99t make find it?
