CMake 2.8.12-rc1 ready for testing!

I am happy to announce that CMake 2.8.12 has entered the release candidate stage.

You can find the source and binaries here: http://www.cmake.org/files/v2.8/?C=M;O=D
 
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.
  • Introduced: Support for RPATH under OSX

  • CMake: New ALIAS targets feature
