[CMake] Cmake problem on nfs partition

[Patrick Begou]

OK, I think I have found the problem after this holiday's week  ;-) .

It is not NFS nor autofs nor link related. The removing of the begining of my
path is hardcoded in cmake  :-( .

In cmake-2.8.1/Source/kwsys/SystemTools.cxx line 4646.

4645  // Work-around an SGI problem by always adding this mapping:
4646  SystemTools::AddTranslationPath("/tmp_mnt/", "/");

I'm not on SGI but my home directory is nfs automounted on:
 /tmp_mnt/hasources
lack of chance. And ALL the computers of the team are using this Path
to mount the home patition from a HA nfs server  :-(

Removing this line, cmake works fine.
This work-around code for a sgi bug is a little bit crazy but how possible is it
to change it for a better fix to make cmake safer ? This cmake bug can occur for
everybody using "/tmp_mnt" as a mount point....
