Update of /cvsroot/CMake/CMake/Tests/ComplexOneConfig/Executable
In directory public:/mounts/ram/cvs-serv11636/Tests/ComplexOneConfig/Executable

Modified Files:
	complex.cxx 
Log Message:
ENH: Implement linking with paths to library files instead of -L and -l separation.  See bug #3832

  - 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.
