CMake 2.8.12-rc2 ready for testing!

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 21:
  • It is now an error to add relative paths to the INCLUDE_DIRECTORIES target property.
• Introduced CMake Policy 22:
  • 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 23:
  • 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.
