#
# Build binary and source package installers.
#
# Variables common to all CPack generators
# ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
#
# 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:
#
# .. variable:: CPACK_PACKAGE_NAME
#
#  The name of the package (or application). If not specified, defaults to
#  the project name.
#
# .. variable:: CPACK_PACKAGE_VENDOR
#
#  The name of the package vendor. (e.g., "Kitware").
#
# .. 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.
#
# .. variable:: CPACK_PACKAGE_VERSION_MAJOR
#
#  Package major Version
#
# .. variable:: CPACK_PACKAGE_VERSION_MINOR
#
#  Package minor Version
#
# .. variable:: CPACK_PACKAGE_VERSION_PATCH
#
#  Package patch Version
#
# .. 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.
#
# .. variable:: CPACK_PACKAGE_DESCRIPTION_SUMMARY
#
#  Short description of the project (only a few words).
#
# .. 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}.
#
# .. 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.
#
# .. variable:: CPACK_PACKAGE_ICON
#
#  A branding image that will be displayed inside the installer (used by GUI
#  installers).
#
# .. 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.
#
# .. 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.
#
# .. 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.
#
# .. 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.
#
# .. 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.
#
# .. 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
#
# .. 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.
#
# .. 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).
#
# .. 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).
#
# 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.
#
# .. 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).
#
# .. 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.
#
# .. 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.
#
# .. 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.*
#
# 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.
#
# .. 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.
#
# .. variable:: CPACK_SYSTEM_NAME
#
#  System name, defaults to the value of ${CMAKE_SYSTEM_NAME}.
#
# .. 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.
#
# .. variable:: CPACK_TOPLEVEL_TAG
#
#  Directory for the installed files.
#
# .. variable:: CPACK_INSTALL_COMMANDS
#
#  Extra commands to install components.
#
# .. variable:: CPACK_INSTALLED_DIRECTORIES
#
#  Extra directories to install.
#
# .. variable:: CPACK_PACKAGE_INSTALL_REGISTRY_KEY
#
#  Registry key used when installing this project. This is only used by
#  installer for Windows.  The default value is based on the installation
#  directory.
#
# .. variable:: CPACK_CREATE_DESKTOP_LINKS
#
#  List of desktop links to create.
