It is using gcc coverage.  If you look at the build notes for that 
machine you can see how it is done:

CMAKE_CXX_FLAGS:STRING=-g -O0 -Wall -W -Wshadow -Wunused-variable 
-Wunused-parameter -Wunused-function -Wunused -Wno-system-headers 
-Wno-deprecated -Woverloaded-virtual -fprofile-arcs -ftest-coverage
CMAKE_C_FLAGS:STRING=-g -O0 -Wall -W -fprofile-arcs -ftest-coverage

Basically, ctest always looks for coverage, so to enable it, you just 
have to build with the right flags, and it should work.
