Kind of.  It looks like gtags does that, so I followed its example.  It might
be better to only include those explicitly listed by, but I
wasn't sure of the best way to get the full list of source files...  OTOH,
maybe it's best to index the whole project.

Probably gtags is not implemented very well.

It seems like there should be a rule to collect the source file list from all Makefiles (including subordinate Makefiles) followed-up by another rule which actually executes cscope using the file list.

If the build is a VPATH build, then the source directory tree should be treated as read-only, with the cscope database being built in the build directory. This allows multiple architectures to use cscope without trashing each other's databases (the cscope database format appears to be architecture dependent).

Indexing everything under the source tree doesn't make sense since the software may not be related, or there may replicated source files.
