##section Variables specific to CPack RPM generator
##end
##module
# - The builtin (binary) CPack RPM generator (Unix only)
# CPackRPM may be used to create RPM package using CPack.
# CPackRPM is a CPack generator thus it uses the CPACK_XXX variables
# used by CPack : http://www.cmake.org/Wiki/CMake:CPackConfiguration
#
# However CPackRPM has specific features which are controlled by
# the specifics CPACK_RPM_XXX variables. CPackRPM is a component aware
# generator so when CPACK_RPM_COMPONENT_INSTALL is ON some more
# CPACK_RPM_<ComponentName>_XXXX variables may be used in order
# to have component specific values. Note however that <componentName>
# refers to the **grouping name**. This may be either a component name
# or a component GROUP name.
# Usually those vars correspond to RPM spec file entities, one may find
# information about spec files here http://www.rpm.org/wiki/Docs.
# You'll find a detailed usage of CPackRPM on the wiki:
#  http://www.cmake.org/Wiki/CMake:CPackPackageGenerators#RPM_.28Unix_Only.29
# However as a handy reminder here comes the list of specific variables:
##end
#
##variable
#  CPACK_RPM_PACKAGE_SUMMARY - The RPM package summary.
#     Mandatory : YES
#     Default   : CPACK_PACKAGE_DESCRIPTION_SUMMARY
##end
##variable
#  CPACK_RPM_PACKAGE_NAME - The RPM package name.
#     Mandatory : YES
#     Default   : CPACK_PACKAGE_NAME
##end
##variable
#  CPACK_RPM_PACKAGE_VERSION - The RPM package version.
#     Mandatory : YES
#     Default   : CPACK_PACKAGE_VERSION
##end
##variable
#  CPACK_RPM_PACKAGE_ARCHITECTURE - The RPM package architecture.
#     Mandatory : NO
#     Default   : -
#     This may be set to "noarch" if you
#     know you are building a noarch package.
##end
##variable
#  CPACK_RPM_PACKAGE_RELEASE - The RPM package release.
#     Mandatory : YES
#     Default   : 1
#     This is the numbering of the RPM package
#     itself, i.e. the version of the packaging and not the version of the
#     content (see CPACK_RPM_PACKAGE_VERSION). One may change the default
#     value if the previous packaging was buggy and/or you want to put here
#     a fancy Linux distro specific numbering.
##end
##variable
#  CPACK_RPM_PACKAGE_LICENSE - The RPM package license policy.
#     Mandatory : YES
#     Default   : "unknown"
##end
##variable
#  CPACK_RPM_PACKAGE_GROUP - The RPM package group.
#     Mandatory : YES
#     Default   : "unknown"
##end
##variable
#  CPACK_RPM_PACKAGE_VENDOR - The RPM package vendor.
#     Mandatory : YES
#     Default   : CPACK_PACKAGE_VENDOR if set or "unknown"
##end
##variable
#  CPACK_RPM_PACKAGE_URL - The projects URL.
#     Mandatory : NO
#     Default   : -
##end
##variable
#  CPACK_RPM_PACKAGE_DESCRIPTION - RPM package description.
#     Mandatory : YES
#     Default   : CPACK_PACKAGE_DESCRIPTION_FILE if set or "no package description available"
##end
##variable
#  CPACK_RPM_COMPRESSION_TYPE - RPM compression type.
#     Mandatory : NO
#     Default   : -
#     May be used to override RPM compression type to be used
#     to build the RPM. For example some Linux distribution now default
#     to lzma or xz compression whereas older cannot use such RPM.
#     Using this one can enforce compression type to be used.
#     Possible value are: lzma, xz, bzip2 and gzip.
##end
##variable
#  CPACK_RPM_PACKAGE_REQUIRES - RPM spec requires field.
#     Mandatory : NO
#     Default   : -
#     May be used to set RPM dependencies (requires).
#     Note that you must enclose the complete requires string between quotes,
#     for example:
#     set(CPACK_RPM_PACKAGE_REQUIRES "python >= 2.5.0, cmake >= 2.8")
#     The required package list of an RPM file could be printed with
#     rpm -qp --requires file.rpm
##end
##variable
#  CPACK_RPM_PACKAGE_SUGGESTS - RPM spec suggest field.
#     Mandatory : NO
#     Default   : -
#     May be used to set weak RPM dependencies (suggests).
#     Note that you must enclose the complete requires string between quotes.
##end
##variable
#  CPACK_RPM_PACKAGE_PROVIDES - RPM spec provides field.
#     Mandatory : NO
#     Default   : -
#     May be used to set RPM dependencies (provides).
#     The provided package list of an RPM file could be printed with
#     rpm -qp --provides file.rpm
##end
##variable
#  CPACK_RPM_PACKAGE_OBSOLETES - RPM spec obsoletes field.
#     Mandatory : NO
#     Default   : -
#     May be used to set RPM packages that are obsoleted by this one.
##end
##variable
#  CPACK_RPM_PACKAGE_RELOCATABLE - build a relocatable RPM.
#     Mandatory : NO
#     Default   : CPACK_PACKAGE_RELOCATABLE
#     If this variable is set to TRUE or ON CPackRPM will try
#     to build a relocatable RPM package. A relocatable RPM may
#     be installed using rpm --prefix or --relocate in order to
#     install it at an alternate place see rpm(8).
#     Note that currently this may fail if CPACK_SET_DESTDIR is set to ON.
#     If CPACK_SET_DESTDIR is set then you will get a warning message
#     but if there is file installed with absolute path you'll get
#     unexpected behavior.
##end
##variable
#  CPACK_RPM_SPEC_INSTALL_POST - [deprecated].
#     Mandatory : NO
#     Default   : -
#     This way of specifying post-install script is deprecated use
#     CPACK_RPM_POST_INSTALL_SCRIPT_FILE
#     May be used to set an RPM post-install command inside the spec file.
#     For example setting it to "/bin/true" may be used to prevent
#     rpmbuild to strip binaries.
##end
##variable
#  CPACK_RPM_SPEC_MORE_DEFINE - RPM extended spec definitions lines.
#     Mandatory : NO
#     Default   : -
#     May be used to add any %define lines to the generated spec file.
##end
##variable
#  CPACK_RPM_PACKAGE_DEBUG - Toggle CPackRPM debug output.
#     Mandatory : NO
#     Default   : -
#     May be set when invoking cpack in order to trace debug information
#     during CPack RPM run. For example you may launch CPack like this
#     cpack -D CPACK_RPM_PACKAGE_DEBUG=1 -G RPM
##end
##variable
#  CPACK_RPM_USER_BINARY_SPECFILE - A user provided spec file.
#     Mandatory : NO
#     Default   : -
#     May be set by the user in order to specify a USER binary spec file
#     to be used by CPackRPM instead of generating the file.
#     The specified file will be processed by configure_file( @ONLY).
#     One can provide a component specific file by setting
#     CPACK_RPM_<componentName>_USER_BINARY_SPECFILE.
##end
##variable
#  CPACK_RPM_GENERATE_USER_BINARY_SPECFILE_TEMPLATE - Spec file template.
#     Mandatory : NO
#     Default   : -
#     If set CPack will generate a template for USER specified binary
#     spec file and stop with an error. For example launch CPack like this
#     cpack -D CPACK_RPM_GENERATE_USER_BINARY_SPECFILE_TEMPLATE=1 -G RPM
#     The user may then use this file in order to hand-craft is own
#     binary spec file which may be used with CPACK_RPM_USER_BINARY_SPECFILE.
##end
##variable
#  CPACK_RPM_PRE_INSTALL_SCRIPT_FILE
#  CPACK_RPM_PRE_UNINSTALL_SCRIPT_FILE
#     Mandatory : NO
#     Default   : -
#     May be used to embed a pre (un)installation script in the spec file.
#     The refered script file(s) will be read and directly
#     put after the %pre or %preun section
#     If CPACK_RPM_COMPONENT_INSTALL is set to ON the (un)install script for
#     each component can be overridden with
#     CPACK_RPM_<COMPONENT>_PRE_INSTALL_SCRIPT_FILE and
#     CPACK_RPM_<COMPONENT>_PRE_UNINSTALL_SCRIPT_FILE
#     One may verify which scriptlet has been included with
#      rpm -qp --scripts  package.rpm
##end
##variable
#  CPACK_RPM_POST_INSTALL_SCRIPT_FILE
#  CPACK_RPM_POST_UNINSTALL_SCRIPT_FILE
#     Mandatory : NO
#     Default   : -
#     May be used to embed a post (un)installation script in the spec file.
#     The refered script file(s) will be read and directly
#     put after the %post or %postun section
#     If CPACK_RPM_COMPONENT_INSTALL is set to ON the (un)install script for
#     each component can be overridden with
#     CPACK_RPM_<COMPONENT>_POST_INSTALL_SCRIPT_FILE and
#     CPACK_RPM_<COMPONENT>_POST_UNINSTALL_SCRIPT_FILE
#     One may verify which scriptlet has been included with
#      rpm -qp --scripts  package.rpm
##end
##variable
#  CPACK_RPM_USER_FILELIST
#  CPACK_RPM_<COMPONENT>_USER_FILELIST
#     Mandatory : NO
#     Default   : -
#     May be used to explicitly specify %(<directive>) file line
#     in the spec file. Like %config(noreplace) or any other directive
#     that be found in the %files section. Since CPackRPM is generating
#     the list of files (and directories) the user specified files of
#     the CPACK_RPM_<COMPONENT>_USER_FILELIST list will be removed from the generated list.
##end
##variable
#  CPACK_RPM_CHANGELOG_FILE - RPM changelog file.
#     Mandatory : NO
#     Default   : -
#     May be used to embed a changelog in the spec file.
#     The refered file will be read and directly put after the %changelog
#     section.
##end
##variable
#  CPACK_RPM_EXCLUDE_FROM_AUTO_FILELIST - list of path to be excluded.
#     Mandatory : NO
#     Default   : /etc /etc/init.d /usr /usr/share /usr/share/doc /usr/bin /usr/lib /usr/lib64 /usr/include
#     May be used to exclude path (directories or files) from the auto-generated
#     list of paths discovered by CPack RPM. The defaut value contains a reasonable
#     set of values if the variable is not defined by the user. If the variable
#     is defined by the user then CPackRPM will NOT any of the default path.
#     If you want to add some path to the default list then you can use
#     CPACK_RPM_EXCLUDE_FROM_AUTO_FILELIST_ADDITION variable.
##end
##variable
#  CPACK_RPM_EXCLUDE_FROM_AUTO_FILELIST_ADDITION - additional list of path to be excluded.
#     Mandatory : NO
#     Default   : -
#     May be used to add more exclude path (directories or files) from the initial
#     default list of excluded paths. See CPACK_RPM_EXCLUDE_FROM_AUTO_FILELIST.
