+CPack FreeBSD Generator
+-----------------------
+
+The built in (binary) CPack FreeBSD (pkg) generator (Unix only)
+
+Variables specific to CPack FreeBSD (pkg) generator
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The CPack FreeBSD generator may be used to create pkg(8) packages -- these may
+be used on FreeBSD, DragonflyBSD, NetBSD, OpenBSD, but also on Linux or OSX,
+depending on the installed package-management tools -- using :module:`CPack`.
+
+The CPack FreeBSD generator is a :module:`CPack` generator and uses the
+``CPACK_XXX`` variables used by :module:`CPack`. It tries to re-use packaging
+information that may already be specified for Debian packages for the
+:cpack_gen:`CPack DEB Generator`. It also tries to re-use RPM packaging
+information when Debian does not specify.
+
+The CPack FreeBSD generator should work on any host with libpkg installed. The
+packages it produces are specific to the host architecture and ABI.
+
+The CPack FreeBSD generator sets package-metadata through
+``CPACK_FREEBSD_XXX`` variables. The CPack FreeBSD generator, unlike the
+CPack Deb generator, does not specially support componentized packages; a
+single package is created from all the software artifacts created through
+CMake.
+
+All of the variables can be set specifically for FreeBSD packaging in
+the CPackConfig file or in CMakeLists.txt, but most of them have defaults
+that use general settings (e.g. CMAKE_PROJECT_NAME) or Debian-specific
+variables when those make sense (e.g. the homepage of an upstream project
+is usually unchanged by the flavor of packaging). When there is no Debian
+information to fall back on, but the RPM packaging has it, fall back to
+the RPM information (e.g. package license).
+
+.. variable:: CPACK_FREEBSD_PACKAGE_NAME
+
+ Sets the package name (in the package manifest, but also affects the
+ output filename).
+
+ * Mandatory: YES
+ * Default:
+
+ - :variable:`CPACK_PACKAGE_NAME` (this is always set by CPack itself,
+ based on CMAKE_PROJECT_NAME).
+
+.. variable:: CPACK_FREEBSD_PACKAGE_COMMENT
+
+ Sets the package comment. This is the short description displayed by
+ pkg(8) in standard "pkg info" output.
+
+ * Mandatory: YES
+ * Default:
+
+ - :variable:`CPACK_PACKAGE_DESCRIPTION_SUMMARY` (this is always set
+ by CPack itself, if nothing else sets it explicitly).
+ - :variable:`PROJECT_DESCRIPTION` (this can be set with the DESCRIPTION
+ parameter for :command:`project`).
+
+.. variable:: CPACK_FREEBSD_PACKAGE_DESCRIPTION
+
+ Sets the package description. This is the long description of the package,
+ given by "pkg info" with a specific package as argument.
+
+ * Mandatory: YES
+ * Default:
+
+ - :variable:`CPACK_DEBIAN_PACKAGE_DESCRIPTION` (this may be set already
+ for Debian packaging, so we may as well re-use it).
+
+.. variable:: CPACK_FREEBSD_PACKAGE_WWW
+
+ The URL of the web site for this package, preferably (when applicable) the
+ site from which the original source can be obtained and any additional
+ upstream documentation or information may be found.
+
+ * Mandatory: YES
+ * Default:
+
+ - :variable:`CMAKE_PROJECT_HOMEPAGE_URL`, or if that is not set,
+ :variable:`CPACK_DEBIAN_PACKAGE_HOMEPAGE` (this may be set already
+ for Debian packaging, so we may as well re-use it).
+
+.. variable:: CPACK_FREEBSD_PACKAGE_LICENSE
+
+ The license, or licenses, which apply to this software package. This must
+ be one or more license-identifiers that pkg recognizes as acceptable license
+ identifiers (e.g. "GPLv2").
+
+ * Mandatory: YES
+ * Default:
+
+ - :variable:`CPACK_RPM_PACKAGE_LICENSE`
+
+.. variable:: CPACK_FREEBSD_PACKAGE_LICENSE_LOGIC
+
+ This variable is only of importance if there is more than one license.
+ The default is "single", which is only applicable to a single license.
+ Other acceptable values are determined by pkg -- those are "dual" or "multi" --
+ meaning choice (OR) or simultaneous (AND) application of the licenses.
+
+ * Mandatory: NO
+ * Default: single
+
+.. variable:: CPACK_FREEBSD_PACKAGE_MAINTAINER
+
+ The FreeBSD maintainer (e.g. kde@freebsd.org) of this package.
+
+ * Mandatory: YES
+ * Default: none
+
+.. variable:: CPACK_FREEBSD_PACKAGE_ORIGIN
+
+ The origin (ports label) of this package; for packages built by CPack
+ outside of the ports system this is of less importance. The default
+ puts the package somewhere under misc/, as a stopgap.
+
+ * Mandatory: YES
+ * Default: misc/<package name>
+
+.. variable:: CPACK_FREEBSD_PACKAGE_CATEGORIES
+
+ The ports categories where this package lives (if it were to be built
+ from ports). If none is set a single category is determined based on
+ the package origin.
+
+ * Mandatory: YES
+ * Default: derived from ORIGIN
+
+.. variable:: CPACK_FREEBSD_PACKAGE_DEPS
+
+ A list of package origins that should be added as package dependencies.
+ These are in the form <category>/<packagename>, e.g. x11/libkonq.
+ No version information needs to be provided (this is not included
+ in the manifest).
+
+ * Mandatory: NO
+ * Default: empty
