This error happens because the way these tests are configured is different 
from how they were before. Previously they had their source in the source dir, 
and their build in the build dir. But since the CMakeLists.txt and similar 
files of all these tests were nearly identical this has changed. Now the 
source tree is in the build dir and this tests do an in-source build there.

You have used the same build dir before, and it still points to the (now gone) 
source location in the source tree. So just wipe the directories of these 
subtests (i.e. the stuff in /usr/BUILD/BuildCmakeGit/Tests/CTestTestMemcheck) 
and rerun these tests, they should work then.
