CMake: different fix for ALIAS issues with 3.10 ALIAS is not really functional in 3.10, so use a variable to approximate the same behaviour. Not elegant but it seems to work.

SetupSwiftLibraries.cmake requires a global variable libEvent_target. However, while the PKGConfig variant of FindLibEvent.cmake did set this, the Win32 variant did not; therefore CMake would always fail to find libEvent, disabling Swift. Therefore I set this property, restoring proper compilation of Swift on Windows systems.
