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).
List of CPack NuGet generator specific variables:
.. variable:: CPACK_NUGET_COMPONENT_INSTALL

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.
