Summary

0015832: ALIAS target scope regression

Description

The commit
    c389f8bb07e900d805ca3163f47b06e3dbe4303b cmLocalGenerator: Port Find method away from GetGeneratorTarget

seems to have broken the following reduced test case:
  cmake_minimum_required(VERSION 3.3)

  project(Foo CXX)

  file(WRITE sub/CMakeLists.txt [[
      file(WRITE foo.cpp "")

      add_library(foo STATIC foo.cpp)
      add_library(Foo::foo ALIAS foo)
  ]])

  add_subdirectory(sub)

  add_custom_target(bar ALL ${CMAKE_COMMAND} -E echo $<TARGET_FILE:Foo::foo>)

At generation time this now produces the diagnostic:

  CMake Error at CMakeLists.txt:14 (add_custom_target):
    Error evaluating generator expression:

      $<TARGET_FILE:Foo::foo>

    No target "Foo::foo"
