| ------- | |
| 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. | |
