# - Try to find libtorrent-rasterbar
#
# If not using pkg-config, you can pre-set LibtorrentRasterbar_CUSTOM_DEFINITIONS
# for definitions unrelated to Boost's separate compilation (which are already
# decided by the LibtorrentRasterbar_USE_STATIC_LIBS variable).
#
# Once done this will define
# LibtorrentRasterbar_FOUND - System has libtorrent-rasterbar
# LibtorrentRasterbar_INCLUDE_DIRS - The libtorrent-rasterbar include directories
# LibtorrentRasterbar_LIBRARIES - The libraries needed to use libtorrent-rasterbar
# LibtorrentRasterbar_DEFINITIONS - Compiler switches required for using libtorrent-rasterbar
# LibtorrentRasterbar_OPENSSL_ENABLED - libtorrent-rasterbar uses and links against OpenSSL
