Brad King 4e3cf8b012 cmOrderDirectories: Reduce repeat realpath() calls
Since commit v3.1.0-rc1~110^2 (Tolerate symlinks during RPATH ordering,
2014-09-09) we call realpath() for every directory ordering constraint
check.  On some platforms/filesystems this is slow, so memoize the
result of the call for each directory.

Ben Boeckel 270eb96df0 strings: Remove cmStdString references
Casts from std::string -> cmStdString were high on the list of things
taking up time. Avoid such implicit casts across function calls by just
using std::string everywhere.

The comment that the symbol name is too long is no longer relevant since
modern debuggers alias the templates anyways and the size is a
non-issue since the underlying methods are generated since it's
inherited.

Stephen Kelly c4373b33b2 cmTarget: Make GetProperty() const.
This has follow-on effects for other methods and classes. Further
work on making the use of const cmTarget pointers common can be
done, particularly with a view to generate-time methods.

Brad King 96afb12087 Convert CMake to OSI-approved BSD License
This converts the CMake license to a pure 3-clause OSI-approved BSD
License.  We drop the previous license clause requiring modified
versions to be plainly marked.  We also update the CMake copyright to
cover the full development time range.

Brad King 0de8be8b49 ENH: Link runtime libraries of all languages
This adds implicit libraries and search directories for languages linked
into a target other than the linker language to its link line.  For
example, when linking an executable containing both C++ and Fortran code
the C++ linker is used but we need to add the Fortran libraries.

The variables

  CMAKE_<LANG>_IMPLICIT_LINK_LIBRARIES
  CMAKE_<LANG>_IMPLICIT_LINK_DIRECTORIES

contain the implicit libraries and directories for each language.
Entries for the linker language are known to be implicit in the
generated link line.  Entries for other languages that do not appear in
the known implicit set are listed explicitly at the end of the link
line.

Brad King d60608c858 STYLE: Factor CollectOriginalDirectories code
This factors code out of cmOrderDirectories::CollectOriginalDirectories
into cmOrderDirectories::AddOriginalDirectories.  Later a new call will
be added, and this is more readable anyway.

Brad King f8f5dde2ee ENH: Warn when system libraries may be hidden.
We never explicitly specify system library directories in linker or
runtime search paths.  Furthermore, libraries in these directories are
always linked by asking the linker to search for them.  We need to
generate a warning when explicitly specified search directories contain
files that may hide the system libraries during the search.

Brad King fd37a6ec3d ENH: Better linker search path computation.
- Use linker search path -L.. -lfoo for lib w/out soname
    when platform sets CMAKE_PLATFORM_USES_PATH_WHEN_NO_SONAME
  - Rename cmOrderRuntimeDirectories to cmOrderDirectories
    and generalize it for both soname constraints and link
    library constraints
  - Use cmOrderDirectories to order -L directories based
    on all needed constraints
  - Avoid processing implicit link directories
  - For CMAKE_OLD_LINK_PATHS add constraints from libs
    producing them to produce old ordering
