CLI: Suppress the unused warning if the key value pair is cached. It is common to specify a CMAKE_TOOLCHAIN_FILE and get a warning for using it despite it not being used. The WarnUnusedCliUnused test relies on the warning being emitted each time cmake is run on an existing build. That behavior is changed by this patch to warn only on the first invokation of CMake, and not on subsequent invokations (because the variable is in the cache with the same value). For that test, a clean target is added which clears the cache and cause the warning to be emitted each time. As the Ninja generator does not support the feature needed to test this, it is not tested with that generator. 2013-05-16 19:51:45 +00:00			`#ifdef _WIN32`
