I'd like to add a new directory named CAP at MonetDBRoot/sql/backends/monet5
The new directory contains cap.c, cap.h, cap.mal, 80_cap.mal, 80_cap.sql, and makefile.ag
I modified MonetDBRoot/sql/backends/monet5/Makefile.ag at:
SUBDIRS = NOT_WIN32?vaults UDF CAP LSST ENABLE_DATACELL?datacell

However, when I run MonetDBRoot/bootstrap, i got the following error message:
...

Any idea please?
