# Ryzom Core
#  Authors: Nevrax and the Ryzom Core Community
#  Version: 0.12.0
#
# Notes:
#   * Changing install location: add -DCMAKE_INSTALL_PREFIX:PATH=/my/new/path
#   * Changing specific install location variables:
#       * NL_ETC_PREFIX (default: $CMAKE_INSTALL_PREFIX/etc)
#       * NL_SHARE_PREFIX (default: $CMAKE_INSTALL_PREFIX/share)
#       * NL_BIN_PREFIX (default: $CMAKE_INSTALL_PREFIX/bin)
#       * NL_SBIN_PREFIX  (default: $CMAKE_INSTALL_PREFIX/sbin)
#       * NL_LIB_PREFIX  (default: $CMAKE_INSTALL_PREFIX/lib)
#       * NL_DRIVER_PREFIX  (default: $CMAKE_INSTALL_PREFIX/lib (windows) or $CMAKE_INSTALL_PREFIX/lib/nel)
#   * Enable building of documentation: add -DBUILD_DOCUMENTATION:BOOL=ON - new make target: DoxygenDoc
#   * Updating version: update header (above) but also update NL_VERSION below.
#   * To build binary archive, use the 'package' target.
#     To build source archive, use the 'package_source' target.
