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 :variable:!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 (:variable: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 :variable:!CPACK_XXX variables used by :module:CPack.

The CPack NuGet generator has specific features which are controlled by the specifics :variable:!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).

Example usage
^^^^^^^^^^^^^

.. code-block:: cmake

  set(CPACK_GENERATOR NuGet)
  # Set up package metadata
  set(CPACK_PACKAGE_NAME SamplePackage)
  set(CPACK_PACKAGE_VERSION "1.0.0")
  set(CPACK_PACKAGE_VENDOR "Example Inc")
  set(CPACK_NUGET_PACKAGE_AUTHORS "ExampleInc")
  set(CPACK_PACKAGE_DESCRIPTION "A .NET wrapper around the foobar library for frobbling bratchens")
  set(CPACK_PACKAGE_HOMEPAGE_URL "https://www.example.com")
  set(CPACK_NUGET_PACKAGE_REPOSITORY_URL "https://github.com/example/libfoobar.git")
  set(CPACK_NUGET_PACKAGE_REPOSITORY_TYPE git)
  set(CPACK_NUGET_PACKAGE_LICENSE_EXPRESSION "MIT")
  # Set up dependencies
  set(CPACK_NUGET_PACKAGE_TFMS "net4;net6.0")
  set(CPACK_NUGET_PACKAGE_DEPENDENCIES_net4 "Foo;Bar")
  # NB: If a version number is omitted, the dependency will not be created
  set(CPACK_NUGET_PACKAGE_DEPENDENCIES_net4_Foo_VERSION "1.23")
  set(CPACK_NUGET_PACKAGE_DEPENDENCIES_net4_Bar_VERSION "4.3.2")
  # NB: General dependencies (not framework-specific) go in this variable
  set(CPACK_NUGET_PACKAGE_DEPENDENCIES "Baz")
  set(CPACK_NUGET_PACKAGE_DEPENDENCIES_Baz_VERSION "9.8.6")
  # NB: Since "net6.0" was listed but no dependencies have been specified, an empty group
  # will be added to the nuspec file for this framework. This can be used to address warning NU5128.
