# Finds LabStreamingLayer (LSL) library

# Sets LSL_LIBRARY_DIRS
# Sets LSL_LIBRARIES_RELEASE

# Adds library to target
# Adds include path

# Script @author Jussi T. Lindgren / Inria
#
# @note On Windows, trying to use the debug library of LSL 1.12 in the same way we did with LSL 1.04
# caused an obscure Windows error code when launching the linking app. To sidestep, we use only the 
# LSL release build library for now. To enable the debug lib, the following might be needed on Win 
# in addition to linking the debug lib (but did not seem to be sufficient to make it work):
# SET(CMAKE_CXX_FLAGS_DEBUG "${CMAKE_CXX_FLAGS_DEBUG} -DLSL_DEBUG_BINDINGS")
