I have managed to get this down to 1 - AllTestsInGenTest (Failed) by fixing the paths in the wdt test scripts. When building with Xcode the binaries are in /Debug or /Release folders inside the build folder. e.g. WDT_BINARY="./_bin/wdt/Debug/wdt"

I think the binaries to be tested could be provided to the scripts as arguments and then CMake can fill the arguments in with generator-expressions.
