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. | |
This policy was introduced in CMake version 2.6.1. CMake version | |
|release| warns when the policy is not set and uses ``OLD`` behavior. Use | |
the :command:`cmake_policy` command to set it to ``OLD`` or ``NEW`` explicitly. | |
