Hmm.... are you building the Debug or the Release variant in VS 2005?
Perhaps this flag is only provided with debug (which is probably the
default for NMake Makefiles)?

Ah, good. It looks like this can be set via the CTEST_TEST_TIMEOUT
variable. So, on could use -DCTEST_TEST_TIMEOUT=300 when configuring
CMake to reduce the timeout time to 5 minutes.

But, it's good to know that CTest is doing the right thing (eventually).
