Ben, I think the problem is that some versions of purify are run by 
putting purify in front of the final link line.  Like this:

purify gcc -o foo foo.o

Running this:

purify foo

Will not work.  So, you have to do something like what was suggested.

Another way is something like this:

set (CMAKE_CXX_LINK_EXECUTABLE
     "purify ${CMAKE_CXX_LINK_EXECUTABLE}")
add_executable (foo foo.cxx)
