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.
