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. |
