[cmake-developers] BUG: ALL_BUILD not added to the PREDEFINED_TARGETS_FOLDER

[Taylor Braun-Jones]

For the Visual Studio generator, the ALL_BUILD is not added to the
PREDEFINED_TARGETS_FOLDER ("CMakePredefinedTargets").

Tested on Windows 10 with Visual Studio 2013 using the following
minimal CMakeLists.txt:

cmake_minimum_required(VERSION 3.5)
project(foobar)
set_property(GLOBAL PROPERTY USE_FOLDERS ON)

Targets like ZERO_CHECK, INSTALL, and RUN_TESTS work for me; just not ALL_BUILD.

Thanks,
Taylor
