[CMake] CMake 2.8.12 Released!

[Robert Maynard]

On behalf of myself, Ken, Bill, Brad, David, Alex, Eike, Steve, Eric, Zach,
Ben and the rest of the CMake team from all around the world,
we are pleased to announce that CMake 2.8.12 is now available for download at:
  http://www.cmake.org/files/v2.8/?C=M;O=D

It is also available from the usual download links found on the CMake web site:
http://www.cmake.org/cmake/resources/software.html

We would like to thank the CMake users who reported issues during the
CMake 2.8.12 release cycle. Your contributions are greatly appreciated.

Some of the notable changes in this release are:

- Introduced target_compile_options command
  - Specify compile options to use when compiling a given target. Supports
    PUBLIC, PRIVATE, and INTERFACE options. PRIVATE and PUBLIC items will
    populate the COMPILE_OPTIONS property of the target. PUBLIC and
    INTERFACE items will populate the INTERFACE_COMPILE_OPTIONS property
    of the target. Supports generator expressions.
- Introduced add_compile_options command
  - Adds options to the compiler command line for sources in the
    current directory and below. Supports generator expressions.
- Introduced CMake Policy CMP0021:
    - It is now an error to add relative paths to the INCLUDE_DIRECTORIES
      target property.
- Introduced CMake Policy CMP0022:
  - Target properties matching (IMPORTED_)LINK_INTERFACE_LIBRARIES(_<CONFIG>)
    are ignored, and will no longer be populated by the target_link_libraries
    command. It is now an error to populate the properties directly in user
    code. Instead use the INTERFACE keyword with target_link_libraries, or
    the target property INTERFACE_LINK_LIBRARIES.
- Introduced CMake Policy CMP0023:
  - Plain and keyword target_link_libraries signatures cannot be mixed for a
    given target when this policy is enabled. Once PUBLIC,PRIVATE, or
    INTERFACE keywords are used, all subsequent target_link_libraries calls
    to the target must use one of these keywords.
- Introduced: Support for RPATH under OSX
  - Please see the blog post by Clinton Stimpson about using RPATH on OSX
    (http://www.kitware.com/blog/home/post/510)
