+Subject: [PATCH] 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 fix is simply 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.
+
