>Description:
Reinplacing paths in cmake's Modules directory is a bad idea:
Especially if using cmake for cross development projects
(which is one of cmake's intended use cases)
it's annoying that standard paths are gone and Find* do not work as expected.

In my case, I need /usr/X11R6 which has been reinplaced by /usr/local.

I don't see why leaving X11R6 in the paths should break something
since that path is present on FreeBSD as well.

>How-To-Repeat:

>Fix:
I do not know the syntax possible with ${REINPLACE} yet.
For a sed invoked from the command line I'd use e.g.

s,(/usr/X11R6)([^<space><tab>]*),\1\2 ${LOCALBASE}\2,g

to append LOCALBASE instead of replacing X11R6.
