This is simple CMake find module for libwebsockets library

FindLibWebSockets.cmake

# This module tries to find libWebsockets library and include files
#
# LIBWEBSOCKETS_INCLUDE_DIR, path where to find libwebsockets.h
# LIBWEBSOCKETS_LIBRARY_DIR, path where to find libwebsockets.so
# LIBWEBSOCKETS_LIBRARIES, the library to link against
# LIBWEBSOCKETS_FOUND, If false, do not try to use libWebSockets
#
# This currently works probably only for Linux

FIND_PATH ( LIBWEBSOCKETS_INCLUDE_DIR libwebsockets.h
    /usr/local/include
    /usr/include
)

FIND_LIBRARY ( LIBWEBSOCKETS_LIBRARIES websockets
    /usr/local/lib

Thanks, I added it... it's alot easier to send a patch.

Thanks for this script. Here is a version that is modified in order to properly complain in case libwebsockets are not found:

# This module tries to find libWebsockets library and include files
#
# LIBWEBSOCKETS_INCLUDE_DIR, path where to find libwebsockets.h
# LIBWEBSOCKETS_LIBRARY_DIR, path where to find libwebsockets.so
# LIBWEBSOCKETS_LIBRARIES, the library to link against
# LIBWEBSOCKETS_FOUND, If false, do not try to use libWebSockets
#
# This currently works probably only for Linux
