# CMake module to search for LIBVLC (VLC library)
# Authors: Rohit Yadav <rohityadav89@gmail.com>
# Harald Sitter <apachelogger@ubuntu.com>
#
# If it's found it sets LIBVLC_FOUND to TRUE
# and following variables are set:
# LIBVLC_INCLUDE_DIR
# LIBVLC_LIBRARY
# LIBVLC_VERSION
if(NOT LIBVLC_MIN_VERSION)
set(LIBVLC_MIN_VERSION "0.0")
endif(NOT LIBVLC_MIN_VERSION)
# find_path and find_library normally search standard locations
# before the specified paths. To search non-standard paths first,
# FIND_* is invoked first with specified paths and NO_DEFAULT_PATH
# and then again with no specified paths to search the default
# locations. When an earlier FIND_* succeeds, subsequent FIND_*s
# searching for the same item do nothing.
