-------
|
||
|
|
|
||
|
|
Target names should match a validity pattern.
|
||
|
|
|
||
|
|
CMake 2.8.12 and lower allowed creating targets using :command:`add_library` and
|
||
|
|
:command:`add_executable` with unrestricted choice for the target name. Newer
|
||
|
|
cmake features such as :manual:`cmake-generator-expressions(7)` and some
|
||
|
|
diagnostics expect target names to match a restricted pattern.
|
||
|
|
|
||
|
|
Target names may contain upper and lower case letters, numbers, the underscore
|
||
|
|
character (_), dot(.), plus(+) and minus(-). As a special case, ALIAS
|
||
|
|
targets and INTERFACE library targets may contain two consequtive colons.
|
||
|
|
|
||
|
|
The OLD behavior for this policy is to allow creating targets which do not match
|
||
|
|
the validity pattern. The NEW behavior for this policy is to report an error
|
||
|
|
if an add_* command is used with an invalid target name.
|
||
|
|
|
||
|
|
This policy was introduced in CMake version 3.0.0. CMake version
|
||
|
|
|release| warns when the policy is not set and uses OLD behavior. Use
|
||
|
|
the cmake_policy command to set it to OLD or NEW explicitly.
