-------
|
||
|
|
|
||
|
|
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.
|
||
|
|
|
||
|
|
This policy was introduced in CMake version 2.6.0. 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.
