BUG: CMAKE_EXECUTABLE_RUNTIME_CXX_FLAG should get its default value from CMAKE_SHARED_LIBRARY_RUNTIME_CXX_FLAG, not CMAKE_SHARED_LIBRARY_RUNTIME_C_FLAG.

ENH: Teach find_library to avoid returning library paths in system directories that may be converted to architecture-specific directories by the compiler when it invokes the linker.

  - Work-around bug in Watcom command line parsing for spaces in paths.
  - Add 'library' option before libraries specified by file path.

ENH: add return and break support to cmake, also change basic command invocation signature to be able to return extra informaiton via the cmExecutionStatus class

BUG: Be less aggressive about finding conflicts in the runtime path when the real soname is not known.

ENH: Enable library search path suffix for sparcv9 architecture.  This should be generalized to a platform file later.

BUG: When a library file name is linked without a path make sure the link type is restored after the -l option.

  - This is purely an implementation improvement.  No interface has changed.
  - Create cmComputeLinkInformation class
  - Move and re-implement logic from:
      cmLocalGenerator::ComputeLinkInformation
      cmOrderLinkDirectories
  - Link libraries to targets with their full path (if it is known)
  - Dirs specified with link_directories command still added with -L
  - Make link type specific to library names without paths
    (name libfoo.a without path becomes -Wl,-Bstatic -lfoo)
  - Make directory ordering specific to a runtime path computation feature
    (look for conflicting SONAMEs instead of library names)
  - Implement proper rpath support on HP-UX and AIX.

ENH: Implement version support in the find_package command module mode.  Version numbers provided to the command are converted to variable settings to tell the FindXXX.cmake module what version is requested.  This addresses issue #1645.

BUG: Make sure search paths never have double-slashes.  Leading with two slashes (//) on cygwin looks like a network path and delays while waiting for a non-existent machine.  This file was left out of the previous checkin for this problem.
