[CMake] PREDEFINED_TARGETS_FOLDER and ALL_BUILD Target

[aaron.meadows at thomsonreuters.com]

I looked at the code and the possibility of introducing a policy to
allow the alternate behavior.  Looks quite straight forward, so I ask:

 

What is the policy on adding policies?

So, I wonder if someone would like to jump in on the Policy direction?
Something like:

 

CMP0018: Allow ALL_BUILDS target to be put into the same Solution Folder
as other targets controled by the PREDEFINED_TARGETS_FOLDER property.

Starting with CMake 2.8.5, enabling this policy will allow the
ALL_BUILDS auto-generated target to be moved into a Solution Folder,
controled by the PREDEFINED_TARGETS_FOLDER property.  Enabling this
policy will cause ALL_BUILDS to nolonger be automatically selected as
the Default project in Visual Studio.

This policy was introduced in CMake version 2.8.5.  Use the cmake_policy
command to set it to OLD or NEW explicitly.

Seems like it wouldn't be so hard to do that, and would allow the
(bizarre) old behavior while still allowing a more consistent behavior.

 

Thoughts?
