[CMake] CMake 2.8.11-rc4 ready for testing!

[Robert Maynard]

The CMake 2.8.11 release candidate continues. This is the last RC
unless a critical, must-fix issue is found. 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 Usage Requirements
  - Targets can specify usage requirements for their consumers such as
include directories
    and preprocessor definitions; previously only link dependencies
were supported
  - target_link_libraries(myexe yourlib) can now build myexe sources
with requirements specified
    by yourlib
  - Added target_include_directories and target_compile_definitions
commands with
    PUBLIC/PRIVATE/INTERFACE options
  - See design and development discussion at
    http://community.kde.org/Frameworks/Epics/CMake_target_usage_requirements

- Introduced a Generator Toolset selection for VS >= 10 and Xcode >= 3
  - Tell the IDEs which compiler toolchain to use
  - ex. Use VS 9 tools under VS 10: -G “Visual Studio 10” -T “v90”
- Introduced ExternalData Module
- Keep source trees lightweight by storing data separately
- Reference data unambiguously from source tree by content hash
- Fetch on-demand during build from local or remote resources
- CMake: Sublime Text Generator added that supports both Make and Ninja
- CMake: Added support for Texas Instruments C6 and up compilers
- CMake: Improve OpenBSD support
- CMake: Support for Windows CE with VS 8 and 9 generators
- CPack: Added Support for 64bit NSIS
- CPack: Added WiX Package Generator
- ExternalProject: Will run git fetch less often
- FindBoost: Major overhaul of searching and result caching
- FindCUDA: Now has support for separable compilation
- FindQt4: Overall improvements to finding Qt and importing targets
