# - 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.You'll find a detailed usage 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:
#
# CPACK_RPM_PACKAGE_SUMMARY
# Mandatory : YES
# Default : CPACK_PACKAGE_DESCRIPTION
# The RPM package summary
# CPACK_RPM_PACKAGE_NAME
# Mandatory : YES
# Default : CPACK_PACKAGE_NAME
# The RPM package name
# CPACK_RPM_PACKAGE_VERSION
# Mandatory : YES
# Default : CPACK_PACKAGE_VERSION
# The RPM package version
# CPACK_RPM_PACKAGE_ARCHITECTURE
# Mandatory : NO
# Default : -
# The RPM package architecture. This may be set to "noarch" if you
# know you are building a noarch package.
# CPACK_RPM_PACKAGE_RELEASE
# Mandatory : YES
# Default : 1
# The RPM package release. 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.
# CPACK_RPM_PACKAGE_LICENSE
# Mandatory : YES
# Default : "unknown"
# The RPM package license policy.
# CPACK_RPM_PACKAGE_GROUP
# Mandatory : YES
# Default : "unknown"
# The RPM package group.
# CPACK_RPM_PACKAGE_VENDOR
# Mandatory : YES
# Default : CPACK_PACKAGE_VENDOR if set or"unknown"
# The RPM package group.
# CPACK_RPM_PACKAGE_DESCRIPTION
# Mandatory : YES
# Default : CPACK_PACKAGE_DESCRIPTION_FILE if set or "no package description available"
# CPACK_RPM_PACKAGE_REQUIRES
# Mandatory : NO
# Default : -
# May be used to set RPM dependencies.
# CPACK_RPM_SPEC_INSTALL_POST
# Mandatory : NO
# Default : -
# 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.
# CPACK_RPM_SPEC_MORE_DEFINE
# Mandatory : NO
# Default : -
# May be used to add any %define lines to the generated spec file.
# CPACK_RPM_PACKAGE_DEBUG
# Mandatory : NO
# Default : -
# May be set when invoking cpack in order to trace debug informations
# during CPack RPM run. For example you may launch CPack like this
# cpack -D CPACK_RPM_PACKAGE_DEBUG=1 -G RPM
