-------
Libraries linked by full-path must have a valid library file name.
In CMake 2.4 and below it is possible to write code like
::
target_link_libraries(myexe /full/path/to/somelib)
where ``somelib`` is supposed to be a valid library file name such as
``libsomelib.a`` or ``somelib.lib``. For Makefile generators this
produces an error at build time because the dependency on the full
path cannot be found. For :ref:`Visual Studio Generators` IDE
and :generator:`Xcode` generators this used to
work by accident because CMake would always split off the library
directory and ask the linker to search for the library by name
(``-lsomelib`` or ``somelib.lib``). Despite the failure with Makefiles, some
projects have code like this and build only with Visual Studio and/or Xcode.
This version of CMake prefers to pass the full path directly to the
native build tool, which will fail in this case because it does not
name a valid library file.
This policy determines what to do with full paths that do not appear
to name a valid library file. The ``OLD`` behavior for this policy is to
split the library name from the path and ask the linker to search for
it. The ``NEW`` behavior for this policy is to trust the given path and
pass it directly to the native build tool unchanged.
