[CMake] add_custom_command doesn't automatically recognize target name created with add_library?

[Thomas Sondergaard]

The documentation for cmake-2.8 states:

In CMake 2.6 and above add_custom_command automatically recognizes a 
target name in its COMMAND and DEPENDS options and computes the target 
location. Therefore this property is not needed for creating custom 
commands.

This doesn't seem to work for me with targets create with 
add_library(..). Is that a bug? I'm working around it by using 
get_target_property(... LOCATION).
