Summary0015544: Policy to require cmake_minimum_required() before project()
Description
If a project() command is not written in used code, cmake will generate one.
When invoked, it sets up the toolchain.

The cmake_minimum_required() command must appear before the project()
command, so that the AppleClang compiler id may be set correctly, according
to CMP0025.

Policy CMP0000 requires that the cmake_minimum_required() command must be
used. That policy could be set to REQUIRED_ALWAYS in CMake 4.0. However,
there would still be no enforcement of requiring the project() command to
come after that.

 http://thread.gmane.org/gmane.comp.programming.tools.cmake.devel/9392 [^]

Additionally, issuing the commands in the wrong order means that use of the CMAKE_MINIMUM_REQUIRED variable in files read via project() is not what is expected.

 http://thread.gmane.org/gmane.comp.programming.tools.cmake.devel/13094/focus=13120 [^]

A policy may be added requiring that the project() command be present and come after cmake_minimum_required(), and generating the project() only in OLD behavior.
