Brad King bc30f8b5e6 Fix lookup of an ALIAS target outside aliased target's directory (#16044) ... Refactoring in commit v3.5.0-rc1~272^2~11 (cmTarget: Implement ALIAS in terms of name mapping, 2015-10-25) accidentally introduced logic that assumes ALIAS targets always reference targets in their own directory. Fix this and add a test case. The configure-step fix is that `cmMakefile::FindTarget` should not consider aliases. The purpose of this method is just to look up targets local to a directory. Since ALIAS and normal targets share a namespace we know a locally defined target will never collide with an ALIAS target anyway. The method has 3 call sites, and this change is safe for all of them: * `cmInstallCommand::HandleTargetsMode`: Rejects aliases before the call. * `cmFLTKWrapUICommand::FinalPass`: Should never have considered aliases. * `cmMakefile::FindTargetToUse`: Falls back to a global lookup anyway. The generate-step fix is that `cmLocalGenerator::FindGeneratorTarget` should not consider aliases. This method is the generate-step equivalent to the above. The method has 2 call sites, and this change is safe for both of them: * `cmInstallTargetGenerator::Compute`: Never uses an alias target name. * `cmLocalGenerator::FindGeneratorTargetToUse`: Falls back to global lookup.
