##section Variables common to all CPack generators
##end
##module
# - Build binary and source package installers.
# The CPack module generates binary and source installers in a variety
# of formats using the cpack program. Inclusion of the CPack module
# adds two new targets to the resulting makefiles, package and
# package_source, which build the binary and source installers,
# respectively. The generated binary installers contain everything
# installed via CMake's INSTALL command (and the deprecated
# INSTALL_FILES, INSTALL_PROGRAMS, and INSTALL_TARGETS commands).
#
# For certain kinds of binary installers (including the graphical
# installers on Mac OS X and Windows), CPack generates installers that
# allow users to select individual application components to
# install. See CPackComponent module for that.
#
# The CPACK_GENERATOR variable has different meanings in different
# contexts. In your CMakeLists.txt file, CPACK_GENERATOR is a
# *list of generators*: when run with no other arguments, CPack
# will iterate over that list and produce one package for each
# generator. In a CPACK_PROJECT_CONFIG_FILE, though, CPACK_GENERATOR
# is a *string naming a single generator*. If you need per-cpack-
# generator logic to control *other* cpack settings, then you need
# a CPACK_PROJECT_CONFIG_FILE.
#
# The CMake source tree itself contains a CPACK_PROJECT_CONFIG_FILE.
# See the top level file CMakeCPackOptions.cmake.in for an example.
#
# If set, the CPACK_PROJECT_CONFIG_FILE is included automatically
# on a per-generator basis. It only need contain overrides.
#
# Here's how it works:
#  - cpack runs
#  - it includes CPackConfig.cmake
#  - it iterates over the generators listed in that file's
#    CPACK_GENERATOR list variable (unless told to use just a
#    specific one via -G on the command line...)
#
#  - foreach generator, it then
#    - sets CPACK_GENERATOR to the one currently being iterated
#    - includes the CPACK_PROJECT_CONFIG_FILE
#    - produces the package for that generator
#
# This is the key: For each generator listed in CPACK_GENERATOR
# in CPackConfig.cmake, cpack will *reset* CPACK_GENERATOR
# internally to *the one currently being used* and then include
# the CPACK_PROJECT_CONFIG_FILE.
#
# Before including this CPack module in your CMakeLists.txt file,
# there are a variety of variables that can be set to customize
# the resulting installers. The most commonly-used variables are:
##end
#
##variable
#  CPACK_PACKAGE_NAME - The name of the package (or application). If
#  not specified, defaults to the project name.
##end
#
##variable
#  CPACK_PACKAGE_VENDOR - The name of the package vendor. (e.g.,
#  "Kitware").
##end
#
##variable
#  CPACK_PACKAGE_DIRECTORY - The directory in which CPack is doing its
#  packaging. If it is not set then this will default (internally) to the
#  build dir. This variable may be defined in CPack config file or from
#  the cpack command line option "-B". If set the command line option
#  override the value found in the config file.
##end
#
##variable
#  CPACK_PACKAGE_VERSION_MAJOR - Package major Version
##end
#
##variable
#  CPACK_PACKAGE_VERSION_MINOR - Package minor Version
##end
#
##variable
#  CPACK_PACKAGE_VERSION_PATCH - Package patch Version
##end
#
##variable
#  CPACK_PACKAGE_DESCRIPTION_FILE - A text file used to describe the
#  project. Used, for example, the introduction screen of a
#  CPack-generated Windows installer to describe the project.
##end
#
##variable
#  CPACK_PACKAGE_DESCRIPTION_SUMMARY - Short description of the
#  project (only a few words).
##end
#
##variable
#  CPACK_PACKAGE_FILE_NAME - The name of the package file to generate,
#  not including the extension. For example, cmake-2.6.1-Linux-i686.
#  The default value is
#
#  ${CPACK_PACKAGE_NAME}-${CPACK_PACKAGE_VERSION}-${CPACK_SYSTEM_NAME}.
##end
#
##variable
#  CPACK_PACKAGE_INSTALL_DIRECTORY - Installation directory on the
#  target system. This may be used by some CPack generators
#  like NSIS to create an installation directory e.g., "CMake 2.5"
#  below the installation prefix. All installed element will be
#  put inside this directory.
##end
#
##variable
#   CPACK_PACKAGE_ICON - A branding image that will be displayed inside
#   the installer (used by GUI installers).
##end
#
##variable
#  CPACK_PROJECT_CONFIG_FILE - CPack-time project CPack configuration
#  file. This file included at cpack time, once per
#  generator after CPack has set CPACK_GENERATOR to the actual generator
#  being used. It allows per-generator setting of CPACK_* variables at
#  cpack time.
##end
#
##variable
#  CPACK_RESOURCE_FILE_LICENSE - License to be embedded in the installer. It
#  will typically be displayed to the user by the produced installer
#  (often with an explicit "Accept" button, for graphical installers)
#  prior to installation. This license file is NOT added to installed
#  file but is used by some CPack generators like NSIS. If you want
#  to install a license file (may be the same as this one)
#  along with your project you must add an appropriate CMake INSTALL
#  command in your CMakeLists.txt.
##end
#
##variable
#  CPACK_RESOURCE_FILE_README - ReadMe file to be embedded in the installer. It
#  typically describes in some detail the purpose of the project
#  during the installation. Not all CPack generators uses
#  this file.
##end
#
##variable
#  CPACK_RESOURCE_FILE_WELCOME - Welcome file to be embedded in the
#  installer. It welcomes users to this installer.
#  Typically used in the graphical installers on Windows and Mac OS X.
##end
#
##variable
#  CPACK_MONOLITHIC_INSTALL - Disables the component-based
#  installation mechanism. When set the component specification is ignored
#  and all installed items are put in a single "MONOLITHIC" package.
#  Some CPack generators do monolithic packaging by default and
#  may be asked to do component packaging by setting
#  CPACK_<GENNAME>_COMPONENT_INSTALL to 1/TRUE.
##end
#
##variable
#  CPACK_GENERATOR - List of CPack generators to use. If not
#  specified, CPack will create a set of options CPACK_BINARY_<GENNAME> (e.g.,
#  CPACK_BINARY_NSIS) allowing the user to enable/disable individual
#  generators. This variable may be used on the command line
#  as well as in:
#
#    cpack -D CPACK_GENERATOR="ZIP;TGZ" /path/to/build/tree
##end
#
##variable
#  CPACK_OUTPUT_CONFIG_FILE - The name of the CPack binary configuration
#  file. This file is the CPack configuration generated by the CPack module
#  for binary installers. Defaults to CPackConfig.cmake.
##end
#
##variable
#  CPACK_PACKAGE_EXECUTABLES - Lists each of the executables and associated
#  text label to be used to create Start Menu shortcuts. For example,
#  setting this to the list ccmake;CMake will
#  create a shortcut named "CMake" that will execute the installed
#  executable ccmake. Not all CPack generators use it (at least NSIS and
#  OSXX11 do).
##end
#
##variable
#  CPACK_STRIP_FILES - List of files to be stripped. Starting with
#  CMake 2.6.0 CPACK_STRIP_FILES will be a boolean variable which
#  enables stripping of all files (a list of files evaluates to TRUE
#  in CMake, so this change is compatible).
##end
#
# The following CPack variables are specific to source packages, and
# will not affect binary packages:
#
##variable
#  CPACK_SOURCE_PACKAGE_FILE_NAME - The name of the source package. For
#  example cmake-2.6.1.
##end
#
##variable
#  CPACK_SOURCE_STRIP_FILES - List of files in the source tree that
#  will be stripped. Starting with CMake 2.6.0
#  CPACK_SOURCE_STRIP_FILES will be a boolean variable which enables
#  stripping of all files (a list of files evaluates to TRUE in CMake,
#  so this change is compatible).
##end
#
##variable
#  CPACK_SOURCE_GENERATOR - List of generators used for the source
#  packages. As with CPACK_GENERATOR, if this is not specified then
#  CPack will create a set of options (e.g., CPACK_SOURCE_ZIP)
#  allowing users to select which packages will be generated.
##end
#
##variable
#  CPACK_SOURCE_OUTPUT_CONFIG_FILE - The name of the CPack source
#  configuration file. This file is the CPack configuration generated by the
#  CPack module for source installers. Defaults to CPackSourceConfig.cmake.
##end
#
##variable
#  CPACK_SOURCE_IGNORE_FILES - Pattern of files in the source tree
#  that won't be packaged when building a source package. This is a
#  list of regular expression patterns (that must be properly escaped),
#  e.g., /CVS/;/\\.svn/;\\.swp$;\\.#;/#;.*~;cscope.*
##end
#
# The following variables are for advanced uses of CPack:
#
##variable
#  CPACK_CMAKE_GENERATOR - What CMake generator should be used if the
#  project is CMake project. Defaults to the value of CMAKE_GENERATOR
#  few users will want to change this setting.
##end
#
##variable
#  CPACK_INSTALL_CMAKE_PROJECTS - List of four values that specify
#  what project to install. The four values are: Build directory,
#  Project Name, Project Component, Directory. If omitted, CPack will
#  build an installer that installers everything.
##end
#
##variable
#  CPACK_SYSTEM_NAME - System name, defaults to the value of
#  ${CMAKE_SYSTEM_NAME}.
##end
#
##variable
#  CPACK_PACKAGE_VERSION - Package full version, used internally. By
#  default, this is built from CPACK_PACKAGE_VERSION_MAJOR,
#  CPACK_PACKAGE_VERSION_MINOR, and CPACK_PACKAGE_VERSION_PATCH.
##end
#
##variable
#  CPACK_TOPLEVEL_TAG - Directory for the installed files.
##end
#
##variable
#  CPACK_INSTALL_COMMANDS - Extra commands to install components.
##end
#
##variable
#  CPACK_INSTALLED_DIRECTORIES - Extra directories to install.
##end
#
##variable
#   CPACK_PACKAGE_INSTALL_REGISTRY_KEY - Registry key used when
#   installing this project. This is only used
#   by installer for Windows.
##end
##variable
#   CPACK_CREATE_DESKTOP_LINKS - List of desktop links to create.
##end
