What are ALL_BUILD and ZERO_CHECK and do I need them?

ZERO_CHECK will rerun cmake. You can/should execute this after changing something on your CMake files.
ALL_BUILD is simply a target which builds all and everything project in the active solution, I guess one can compare it to "make all".
Add the following line to you CMakeLists.txt to suppress generation of ZERO_CHECK:
set(CMAKE_SUPPRESS_REGENERATION true)
