Doesn't TERMINFO_DIRS do this job?

ncurses(3x):
   TERMINFO_DIRS
     Specifies a list of locations to search for terminal descriptions.
     Each location in the list is a terminal database as described in
     the section on the TERMINFO variable.  The list is separated by
     colons (i.e., ":") on Unix, semicolons on OS/2 EMX.

     There is no corresponding feature in System V terminfo; it is an
     extension developed for ncurses.
