| ------- |
| |
| Target names should not be reserved and should match a validity pattern. |
| |
| CMake 2.8.12 and lower allowed creating targets using :command:`add_library`, |
| :command:`add_executable` and :command:`add_custom_target` 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`` and ``IMPORTED`` targets may contain |
| two consecutive colons. |
| |
| Target names reserved by one or more CMake generators are not allowed. |
| Among others these include ``all``, ``clean``, ``help``, and ``install``. |
| |
| Target names associated with optional features, such as ``test`` and |
| ``package``, may also be reserved. CMake 3.10 and below always reserve them. |
| CMake 3.11 and above reserve them only when the corresponding feature is |
| enabled (e.g. by including the :module:`CTest` or :module:`CPack` modules). |
| |
| The ``OLD`` behavior for this policy is to allow creating targets with |
| reserved names or 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. 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. |
