Some notes about this policy:
1. It warns for targets where a something like this was done:
      set_property ( DIRECTORY . APPEND PROPERTY 
COMPILE_DEFINITIONS_DEBUG TEST_ON )
    -> Maybe warn just once for the direct appearance of this?

2. The CMP0043 descriptions only mentions target specific solutions.

3. I never liked the set_property ( DIRECTORY... ) solution because 
there is also
    and add_definitions() command. In the description of 
add_definitions(), it is
    mentioned:
    "Arguments to add_definitions may use “generator expressions” with 
the syntax “$<...>”."
    However, I tried and this results in broken MSVC10 project files as 
those then contain:
    <AdditionalOptions> ""$"<"$"<CONFIG:Debug>:-DTEST_ON>" 
%(AdditionalOptions)</AdditionalOptions>
