Summary:                    $<TARGET_PROPERTY:prop> with add_custom_target does
not work
Description: 
When using the $<TARGET_PROPERTY:FOO> generator expression inside an
add_custom_target command the following error is produced:

CMake Error at CMakeLists.txt:6 (add_custom_target):
  Error evaluating generator expression:

    $<TARGET_PROPERTY:FOO>

  $<TARGET_PROPERTY:prop> may only be used with targets.  It may not be used
  with add_custom_command.  Specify the target to read a property from using
  the $<TARGET_PROPERTY:tgt,prop> signature instead.

I would expect that with add_custom_target command the short hand form should
work (like error message says already, ... may only be used with targets).

Steps to Reproduce: 
Save this as a CMakeLists.txt and run cmake:

cmake_minimum_required(VERSION 2.8 FATAL_ERROR)

project(Foo NONE)

add_custom_target(foo
    COMMAND ${CMAKE_COMMAND} -E echo $<TARGET_PROPERTY:FOO>
)

set_property(TARGET foo PROPERTY FOO "foobar")


Additional Information: 
Problem exists with cmake version 2.8.12.1, 3.0.20140422-g9f9532, and 
3.0.20140424-gb4aa99
