Summary0014658: Document CMAKE_VERBOSE_MAKEFILE initialization
DescriptionThis may be OS and generator independent. (I've reproduced it on Windows 7 (with MS Visual Studio) and Ubuntu 12.04 (with GNUmake/GCC).)

Using project() in a CMakeLists.txt file causes CMAKE_VERBOSE_MAKEFILE to be 0/False
Steps To Reproduce1. Run cmake on the following (minimal) CMakeLists.txt file.

Result: in the cmake output, the second message reporting the value of CMAKE_VERBOSE_MAKEFILE is "FALSE". (See output below.)

Expected result: in the cmake output, both lines reporting CMAKE_VERBOSE_MAKEFILE should be 1 (or True)

cmake_minimum_required(VERSION 2.8.12) # I'm not sure how far back this bug might go

set(CMAKE_VERBOSE_MAKEFILE 1)

message(STATUS "CMAKE_VERBOSE_MAKEFILE ${CMAKE_VERBOSE_MAKEFILE}")

CMAKE_VERBOSE_MAKEFILE is a cache entry that is initialized by the project() command. It is meant to be set in a local build tree by the user. If you want to override the cache initialization in the project then use

 set(CMAKE_VERBOSE_MAKEFILE 1 CACHE BOOL "Enable verbose make output.")
 project(...)

If you want to override it and ignore the cache entry then use

 project(...)
 set(CMAKE_VERBOSE_MAKEFILE 1)
