We used to call realpath but ended up having to remove it.  The problem
is that people running with network mounted disks can have the
"realpath" corresponding to a logical directory name actually change
between builds.

I'm unable to duplicate this problem.  Would you please build a CMake
from source, but with the following modification?

In Source/cmOrderLinkDirectories.cxx, uncomment the line

  //#define CM_ORDER_LINK_DIRECTORIES_DEBUG

and change the line

  this->Debug = false;

to

  this->Debug = true;

Then re-run cmake on the tree having this problem and send me the output.

Thanks,
