ctest itself treats a nonzero return as failure.  It's pretty trivial to 
run a wrapper to invert the status for expected failures, and customise 
the test running in any way you see fit.  See the EXPECT_FAIL lines in

https://github.com/apache/xerces-c/blob/f7654ee16b1dc2fb6e2b68777895c5384cd51c28/tests/CMakeLists.txt#L176

and the wrapper logic in

https://github.com/apache/xerces-c/blob/f7654ee16b1dc2fb6e2b68777895c5384cd51c28/cmake/RunTest.cmake#L45

as one way to do this.
