# CPackDeb

The builtin (binary) CPack Deb generator (Unix only)

## Variables specific to CPack Debian (DEB) generator

CPackDeb may be used to create Deb package using CPack. CPackDeb is a CPack generator thus it uses the CPACK_XXX variables used by CPack : https://cmake.org/Wiki/CMake:CPackConfiguration. CPackDeb generator should work on any linux host but it will produce better deb package when Debian specific tools ‘dpkg-xxx’ are usable on the build system.

CPackDeb has specific features which are controlled by the specifics `CPACK_DEBIAN_XXX` variables.

`CPACK_DEBIAN_<COMPONENT>_XXXX` variables may be used in order to have component specific values. Note however that <COMPONENT> refers to the grouping name written in upper case. It may be either a component name or a component GROUP name.

You’ll find a detailed usage on the wiki: https://cmake.org/Wiki/CMake:CPackPackageGenerators#DEB_.28UNIX_only.29 . However as a handy reminder here comes the list of specific variables:

`CPACK_DEBIAN_PACKAGE_NAME`

  The Debian package summary

  - Mandatory : YES
  - Default : `CPACK_PACKAGE_NAME` (lower case)

`CPACK_DEBIAN_PACKAGE_VERSION`

  The Debian package version

  - Mandatory : YES
  - Default : `CPACK_PACKAGE_VERSION`

`CPACK_DEBIAN_PACKAGE_ARCHITECTURE`

  The Debian package architecture

  - Mandatory : YES
  - Default : Output of `dpkg --print-architecture` (or `i386` if `dpkg` is not found)

`CPACK_DEBIAN_PACKAGE_DEPENDS`
`CPACK_DEBIAN_<COMPONENT>_PACKAGE_DEPENDS`

  Sets the Debian dependencies of this package.

  - Mandatory : NO
  - Default :
    - An empty string for non-component based installations
    - `CPACK_DEBIAN_PACKAGE_DEPENDS` for component-based installations.

  Note

  If `CPACK_DEBIAN_PACKAGE_SHLIBDEPS` or more specifically `CPACK_DEBIAN_<COMPONENT>_PACKAGE_SHLIBDEPS` is set for this component, the discovered dependencies will be appended to `CPACK_DEBIAN_<COMPONENT>_PACKAGE_DEPENDS` instead of `CPACK_DEBIAN_PACKAGE_DEPENDS`. If `CPACK_DEBIAN_<COMPONENT>_PACKAGE_DEPENDS` is an empty string, only the automatically discovered dependencies will be set for this component.

  Example:

      set(CPACK_DEBIAN_PACKAGE_DEPENDS "libc6 (>= 2.3.1-6), libc6 (< 2.4)")

`CPACK_DEBIAN_PACKAGE_MAINTAINER`

  The Debian package maintainer

  - Mandatory : YES
  - Default : `CPACK_PACKAGE_CONTACT`

`CPACK_DEBIAN_PACKAGE_DESCRIPTION`
`CPACK_COMPONENT_<COMPONENT>_DESCRIPTION`

  The Debian package description

  - Mandatory : YES
  - Default :
    - `CPACK_DEBIAN_PACKAGE_DESCRIPTION` if set or
    - `CPACK_PACKAGE_DESCRIPTION_SUMMARY`

`CPACK_DEBIAN_PACKAGE_SECTION`
  - Mandatory : YES
  - Default : ‘devel’

`CPACK_DEBIAN_COMPRESSION_TYPE`

  The compression used for creating the Debian package. Possible values are: lzma, xz, bzip2 and gzip.

  - Mandatory : YES
  - Default : ‘gzip’

`CPACK_DEBIAN_PACKAGE_PRIORITY`

  The Debian package priority

  - Mandatory : YES
  - Default : ‘optional’

`CPACK_DEBIAN_PACKAGE_HOMEPAGE`

  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 : NO
  - Default : -

  Note

  The content of this field is a simple URL without any surrounding characters such as <>.

`CPACK_DEBIAN_PACKAGE_SHLIBDEPS`
`CPACK_DEBIAN_<COMPONENT>_PACKAGE_SHLIBDEPS`

  May be set to ON in order to use `dpkg-shlibdeps` to generate better package dependency list.

  - Mandatory : NO
  - Default :
    - `CPACK_DEBIAN_PACKAGE_SHLIBDEPS` if set or
    - OFF

  Note

  You may need set `CMAKE_INSTALL_RPATH` to an appropriate value if you use this feature, because if you don’t `dpkg-shlibdeps` may fail to find your own shared libs. See https://cmake.org/Wiki/CMake_RPATH_handling.

`CPACK_DEBIAN_PACKAGE_DEBUG`

  May be set when invoking cpack in order to trace debug information during CPackDeb run.

  - Mandatory : NO
  - Default : -

`CPACK_DEBIAN_PACKAGE_PREDEPENDS`
`CPACK_DEBIAN_<COMPONENT>_PACKAGE_PREDEPENDS`

  Sets the Pre-Depends field of the Debian package. Like `Depends`, except that it also forces `dpkg` to complete installation of the packages named before even starting the installation of the package which declares the pre-dependency.

  - Mandatory : NO
  - Default :
    - An empty string for non-component based installations
    - `CPACK_DEBIAN_PACKAGE_PREDEPENDS` for component-based installations.

  See http://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps

`CPACK_DEBIAN_PACKAGE_ENHANCES`
`CPACK_DEBIAN_<COMPONENT>_PACKAGE_ENHANCES`

  Sets the Enhances field of the Debian package. Similar to `Suggests` but works in the opposite direction: declares that a package can enhance the functionality of another package.

  - Mandatory : NO
  - Default :
    - An empty string for non-component based installations
    - `CPACK_DEBIAN_PACKAGE_ENHANCES` for component-based installations.

  See http://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps

`CPACK_DEBIAN_PACKAGE_BREAKS`
`CPACK_DEBIAN_<COMPONENT>_PACKAGE_BREAKS`

  Sets the Breaks field of the Debian package. When a binary package (P) declares that it breaks other packages (B), `dpkg` will not allow the package (P) which declares Breaks be unpacked unless the packages that will be broken (B) are deconfigured first. As long as the package (P) is configured, the previously deconfigured packages (B) cannot be reconfigured again.

  - Mandatory : NO
  - Default :
    - An empty string for non-component based installations
    - `CPACK_DEBIAN_PACKAGE_BREAKS` for component-based installations.

  See https://www.debian.org/doc/debian-policy/ch-relationships.html#s-breaks

`CPACK_DEBIAN_PACKAGE_CONFLICTS`
`CPACK_DEBIAN_<COMPONENT>_PACKAGE_CONFLICTS`

  Sets the Conflicts field of the Debian package. When one binary package declares a conflict with another using a Conflicts field, `dpkg` will not allow them to be unpacked on the system at the same time.

  - Mandatory : NO
  - Default :
    - An empty string for non-component based installations
    - `CPACK_DEBIAN_PACKAGE_CONFLICTS` for component-based installations.

  See https://www.debian.org/doc/debian-policy/ch-relationships.html#s-conflicts

  Note

  This is a stronger restriction than `Breaks`, which prevents the broken package from being configured while the breaking package is in the “Unpacked” state but allows both packages to be unpacked at the same time.

`CPACK_DEBIAN_PACKAGE_PROVIDES`
`CPACK_DEBIAN_<COMPONENT>_PACKAGE_PROVIDES`

  Sets the Provides field of the Debian package. A virtual package is one which appears in the Provides control field of another package.

  - Mandatory : NO
  - Default :
    - An empty string for non-component based installations
    - `CPACK_DEBIAN_PACKAGE_PROVIDES` for component-based installations.

  See https://www.debian.org/doc/debian-policy/ch-relationships.html#s-virtual

`CPACK_DEBIAN_PACKAGE_REPLACES`
`CPACK_DEBIAN_<COMPONENT>_PACKAGE_REPLACES`

  Sets the Replaces field of the Debian package. Packages can declare in their control file that they should overwrite files in certain other packages, or completely replace other packages.

  - Mandatory : NO
  - Default :
    - An empty string for non-component based installations
    - `CPACK_DEBIAN_PACKAGE_REPLACES` for component-based installations.

  See http://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps

`CPACK_DEBIAN_PACKAGE_RECOMMENDS`
`CPACK_DEBIAN_<COMPONENT>_PACKAGE_RECOMMENDS`

  Sets the Recommends field of the Debian package. Allows packages to declare a strong, but not absolute, dependency on other packages.

  - Mandatory : NO
  - Default :
    - An empty string for non-component based installations
    - `CPACK_DEBIAN_PACKAGE_RECOMMENDS` for component-based installations.

  See http://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps

`CPACK_DEBIAN_PACKAGE_SUGGESTS`
`CPACK_DEBIAN_<COMPONENT>_PACKAGE_SUGGESTS`

  Sets the Suggests field of the Debian package. Allows packages to declare a suggested package install grouping.

  - Mandatory : NO
  - Default :
    - An empty string for non-component based installations
    - `CPACK_DEBIAN_PACKAGE_SUGGESTS` for component-based installations.

  See http://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps

`CPACK_DEBIAN_PACKAGE_CONTROL_EXTRA`
`CPACK_DEBIAN_<COMPONENT>_PACKAGE_CONTROL_EXTRA`

  This variable allow advanced user to add custom script to the control.tar.gz. Typical usage is for conffiles, postinst, postrm, prerm.

  - Mandatory : NO
  - Default : -

  Usage:

      set(CPACK_DEBIAN_PACKAGE_CONTROL_EXTRA
          "${CMAKE_CURRENT_SOURCE_DIR/prerm;${CMAKE_CURRENT_SOURCE_DIR}/postrm")

  Note

  The original permissions of the files will be used in the final package unless the variable `CPACK_DEBIAN_PACKAGE_CONTROL_STRICT_PERMISSION` is set. In particular, the scripts should have the proper executable flag prior to the generation of the package.

`CPACK_DEBIAN_PACKAGE_CONTROL_STRICT_PERMISSION`
`CPACK_DEBIAN_<COMPONENT>_PACKAGE_CONTROL_STRICT_PERMISSION`

  This variable indicates if the Debian policy on control files should be strictly followed.

  - Mandatory : NO
  - Default : FALSE

  Usage:

      set(CPACK_DEBIAN_PACKAGE_CONTROL_STRICT_PERMISSION TRUE)

  Note

  This overrides the permissions on the original files, following the rules set by Debian policy https://www.debian.org/doc/debian-policy/ch-files.html#s-permissions-owners
