+
+  Installs a |SBOM| or "SBOM" which describes the project:
+
+  .. code-block:: cmake
+
+    install(SBOM <sbom-name> EXPORT <export-name>
+            [PROJECT <project-name>|NO_PROJECT_METADATA]
+            [DESTINATION <dir>]

+            [PACKAGE_URL <url-string>]
+            [FORMAT <string>])
+
+  The ``SBOM`` form generates a |SBOM| or "SBOM" file for a given project
+  and installs it as part of the project installation.  A |SBOM| is a
+  machine-readable description of the project's targets, linked libraries,
+  and related metadata, such as versions and license information.  CMake
+  currently generates SBOM files using the |SPDX|_ 3.0 specification in
+  its JSON-LD representation, as selected by the ``FORMAT`` option, but
+  the interface is designed to allow additional SBOM formats or schema
+  versions to be supported in future CMake releases.
+
+  Target installations are associated with the export ``<export-name>``
+  using the ``EXPORT`` option of the :command:`install(TARGETS)` signature
+  documented above. If ``DESTINATION`` is not specified, a platform-specific
+  default is used.
+
+  Several options may be used to specify package metadata:
+
+  ``VERSION <version>``
+    The package version, specified as a series of non-negative  integer components,
+    i.e. <major>[.<minor>[.<patch>[.<tweak>]]].  See :command:`project(VERSION)` for
+    more information.
+
+  ``FORMAT <string>``
+    The format in which the SBOM should be exported, which must be an expression of
+    the form ``<format>[-<version>][+<representation>]``.  CMake currently supports
+    the JSON-LD serialization of |SPDX|_ v3.0.1 (``spdx`` or ``spdx-3.0.1+json``),
+    which is also the default if ``FORMAT`` is not specified.
+
+  ``HOMEPAGE_URL <url-string>``
+
+    An informational canonical home URL for the project.
+
+  ``PACKAGE_URL <url-string>``
+
+    An informational canonical package URL for the project.
+
+  ``LICENSE <license-string>``
+
+    A |SPDX|_ (SPDX) `License Expression`_ that describes the license(s) of the
+    project as a whole, including documentation, resources, or other materials
+    distributed with the project, in addition to software artifacts.  See the
+    SPDX `License List`_ for a list of commonly used licenses and their
+    identifiers.
+
+    The license of individual components is taken from the
+    :prop_tgt:`SPDX_LICENSE` property of their respective targets.
+
+  ``DESCRIPTION <description-string>``
+
+    An informational description of the project.  It is recommended that this
+    description is a relatively short string, usually no more than a few words.
+
+  By default, if the specified ``<package-name>`` matches the current CMake
+  :variable:`PROJECT_NAME`, sbom metadata will be inherited from the
+  project.  The ``PROJECT <project-name>`` option may be used to specify a
+  different project from which to inherit metadata.  If ``NO_PROJECT_METADATA``
+  is specified, automatic inheritance of sbom metadata will be disabled.
+  In any case, any metadata values specified in the ``install`` command will
+  take precedence.
