Every policy's documentation has a paragraph on what version of CMake introduced it, how to set the policy, and whether CMake warns if the policy is not set. The wording of this paragraph has diverged across policies over time. Factor the paragraph out into a standard advice document included by every policy.

-------

Libraries linked may not have leading or trailing whitespace.
|
|
|
|
CMake versions 2.4 and below silently removed leading and trailing
|
|
whitespace from libraries linked with code like
|
|
|
|
::
|
|
|
|
target_link_libraries(myexe " A ")
|
|
|
|
This could lead to subtle errors in user projects.
|
|
|
|
The ``OLD`` behavior for this policy is to silently remove leading and
|
|
trailing whitespace. The ``NEW`` behavior for this policy is to diagnose
|
|
the existence of such whitespace as an error. The setting for this
|
|
policy used when checking the library names is that in effect when the
|
|
target is created by an :command:`add_executable` or :command:`add_library`
|
|
command.
