Summary:                    Generator expressions provide PLATFORM_ID but its
values are not documented
Description: 
http://www.cmake.org/cmake/help/v3.0/manual/cmake-generator-expressions.7.html
documents PLATFORM_ID, but does not mention the possible values the variable
could have.

I suppose the corresponding variable is CMAKE_<LANG>_PLATFORM_ID
http://www.cmake.org/cmake/help/v3.0/variable/CMAKE_LANG_PLATFORM_ID.html, but
is documented as internal.

Removing PLATFORM_ID from generator expressions would be a step backwards since
it would remove an important use case, documentation CMAKE_<LAND>_PLATFORM_ID
seems the right direction.

In general the generator expression documentation could be more explicit about
the corresponding variables.

Steps to Reproduce: 
None.
