         I am using cmake-2.6.3-RC-14-Linux-i386.
     Actually i have a test t1. i want to set and unset LD_LIBRARY_PATH acc.
while adding  test t1 so that on running ctest it will use that value of
LD_LIBRARY_PATH rather than using the older set value.

This iam not able to achieve that.

Guide where iam wrong and what need to be done.
