I do both, but my tendency is to use the install tree a lot more, because of the substantial (factor of two gain in speed for my two-CPU box) advantage of a parallel test infrastructure there that cannot be used with the ctest method; ctest is unaware of the dependencies between tests, and just does the tests in sequence leaving all but one of the CPUs of a multiple CPU box completely idle. N.B. We could also take advantage of the parallel testing possiblity in the build tree if we dropped ctest altogether and instead simply set up our build-tree tests as custom targets with proper dependencies between them. So if you have a multiple cpu box, but don't want to bother with the install tree, then this parallel testing possibility for the build tree would be a good area to work on to allow taking proper advantage of those multiple cpu's for build-tree testing. Of course the above "parallel" testing considerations for both install tree and build tree are only relevant on Windows if there is a Windows CMake generator that allows parallel commands to be executed similar to the GNU make -j option.
