CPack NuGet Generator
---------------------

.. versionadded:: 3.12

When build a NuGet package there is no direct way to control an output
filename due a lack of the corresponding CLI option of NuGet, so there
is no ``CPACK_NUGET_PACKAGE_FILE_NAME`` variable. To form the output filename
NuGet uses the package name and the version according to its built-in rules.

Also, be aware that including a top level directory
(``CPACK_INCLUDE_TOPLEVEL_DIRECTORY``) is ignored by this generator.


Variables specific to CPack NuGet generator
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

The CPack NuGet generator may be used to create NuGet packages using
:module:`CPack`. The CPack NuGet generator is a :module:`CPack` generator thus
it uses the ``CPACK_XXX`` variables used by :module:`CPack`.

The CPack NuGet generator has specific features which are controlled by the
specifics ``CPACK_NUGET_XXX`` variables. In the "one per group" mode
(see :variable:`CPACK_COMPONENTS_GROUPING`), ``<compName>`` placeholder
in the variables below would contain a group name (uppercased and turned into
a "C" identifier).
