CMake 3.0-rc4 now ready for testing!

I am proud to announce the CMake 3.0 fourth release candidate.

Sources and binaries are available at:
  http://www.cmake.org/files/v3.0/?C=M;O=D

Documentation is available at:
  http://www.cmake.org/cmake/help/v3.0

Release notes appear below and are also published at
  http://www.cmake.org/cmake/help/v3.0/release/3.0.0.html

Some of the more significant features of CMake 3.0 are:

  • Compatibility options supporting code written for CMake versions prior to 2.4 have been removed.
  • The CMake language has been extended with *Bracket Argument* and  *Bracket Comment* syntax inspired by Lua long brackets.
  • The CMake documentation has been converted to reStructuredText and uses Sphix generation.
  • Generators for Visual Studio 10 (2010) and later were renamed to include the product year like generators for older VS versions:
    • "Visual Studio 10" -> "Visual Studio 10 2010"
    • "Visual Studio 11" -> "Visual Studio 11 2012"
    • "Visual Studio 12" -> "Visual Studio 12 2013"
  •  This clarifies which generator goes with each Visual Studio version. The old names are recognized for compatibility.
  • A new "CodeLite" extra generator is available for use with the Makefile or Ninja generators.
  • A new "Kate" extra generator is available for use with the Makefile or Ninja generators.
  • The "add_library()" command learned a new "INTERFACE" library type. Interface libraries have no build rules but may have properties defining "usage requirements" and may be installed, exported, and imported.  This is useful to create header-only libraries that have concrete link dependencies on other libraries.
  • The "export()" command learned a new "EXPORT" mode that retrieves the list of targets to export from an export set configured by the "install(TARGETS)" command "EXPORT" option. This makes it easy to export from the build tree the same targets that are exported from the install tree.
  • The "project()" command learned to set some version variables to values specified by the new "VERSION" option or to empty strings. See policy "CMP0048".
  • Several long-outdated commands that should no longer be called have been disallowed in new code by policies:
    • Policy "CMP0029" disallows "subdir_depends()"
    • Policy "CMP0030" disallows "use_mangled_mesa()"
    • Policy "CMP0031" disallows "load_command()"
    • Policy "CMP0032" disallows "output_required_files()"
    • Policy "CMP0033" disallows "export_library_dependencies()"
    • Policy "CMP0034" disallows "utility_source()"
    • Policy "CMP0035" disallows "variable_requires()"
    • Policy "CMP0036" disallows "build_name()"
