ENH: When linking to versioned targets whose real file name is known pass the real name to the linker instead of the symlink name.

  - Cycles may be formed among static libraries
  - Native build system should not have cycles in target deps
  - Create cmComputeTargetDepends to analyze dependencies
  - Identify conneced components and use them to fix deps
  - Diagnose cycles containing non-STATIC targets
  - Add debug mode property GLOBAL_DEPENDS_DEBUG_MODE
  - Use results in cmGlobalGenerator as target direct depends

  - Add NAMELINK_ONLY and NAMELINK_SKIP to INSTALL command
  - Options select a \"namelink\" mode
  - cmInstallTargetGenerator selects files/link based on mode
  - See bug #4419

BUG: Added TARGET_ARCHIVES_MAY_BE_SHARED_LIBS global property to help compute proper rpath information on AIX when shared libraries have names like "libfoo.a".

BUG: When configuring compiler information files into the CMakeFiles directory in the project build tree, use IMMEDIATE option for CONFIGURE_FILE explicitly.  It is needed in case the user sets CMAKE_BACKWARDS_COMPATIBILITY to 2.0 or lower.

BUG: When forcing the C and CXX compilers do not try to detect the ABI information.  Cleanup configured language compiler info files by always using @ONLY.  This addresses bug#6297.

COMP: Avoid warning in kwsys IOStream.cxx when the helper functions are not needed.  Define one public symbol to avoid complaints from archivers about empty object files.

BUG: cmCTest::GetConfigType should return the string by reference-to-const so that callers may use .c_str() safely.

  - NetBSD needs dependent library paths in -rpath-link option.
  - kFreeBSD needs dependent library paths in -rpath-link option.

ENH: really Bill, using Ken's checkout, fix output in ctest so clean output in build and test is not lost, also display the command lines used

BUG:  When preserving relative paths for moc generated files,
      also consider paths to headers in the build directory.

  - Motivation:
    - It depended on the order of installation
    - It supported only a single destination for each target
    - It created directory portions of an install name without user request
  - Updated ExportImport test to install targets in an order that expoed
    this bug

      add Qt release/debug defines.

      Consolidate some strings.

      More responsive interrupting.  Prompt user if they try to close during
      configure, and allow them to close.

  - Build without rpaths
  - Place implementation libs in separate directories
