# - Try to find libtorrent-rasterbar

# If not using pkg-config, you can pre-set LibtorrentRasterbar_CUSTOM_DEFINITIONS
|

# This module tries to locate libtorrent-rasterbar Config.cmake files and uses pkg-config if available
|
||||
# and the config file could not be found.
|
||||
# If that does not work, 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).
