# 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 : http://www.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.You'll find a detailed usage on the wiki:
|
|
# http://www.cmake.org/Wiki/CMake:CPackPackageGenerators#DEB_.28UNIX_only.29
|
|
