LOG: [lldb/CMake] Always set a value for find_package when finding optional dependencies

Because this is a macro, previous values of `find_package` persist
between calls. This means that if it is set to TRUE on any run, all
subsequent runs will have find_package set to TRUE regardles of whether
or not they should be.
