+# This module can be used to find the Superluminal API libs & headers via find_package.
+#
+# For example: find_package(SuperluminalAPI REQUIRED)
+#
+# You can use it by adding the API directory of your Superluminal install to your CMAKE_PREFIX_PATH, or alternatively
+# by copying the entire API directory to a place of your own choosing and adding that location to CMAKE_PREFIX_PATH.
+#
+# The following (optional) variables can be set prior to issueing the find_package command:
+# - SuperluminalAPI_ROOT				: 	The root directory where the libs & headers should be found. For example <SuperluminalInstallDir>\API.
+#						  					If this is not set, the libs & headers are assumed to be next to the location of FindSuperluminalAPI.cmake
+# - SuperluminalAPI_USE_STATIC_RUNTIME	:	If this is set, the libraries linked to the static C runtime (i.e. /MT and /MTd) will be returned
+#											If not set, the libraries linked to the dynamic C runtime (i.e. /MD and /MDd) will be returned
+# 
+# On completion of find_package, the following variables will be set:
+#
+# SuperluminalAPI_FOUND			: Whether the package was found
+# SuperluminalAPI_LIBS_RELEASE	: The Release libraries to link against
+# SuperluminalAPI_LIBS_DEBUG	: The Debug libraries to link against
+# SuperluminalAPI_INCLUDE_DIRS	: The include directories to use
+#
+# In addition, if find_package completed successfully, the target "SuperluminalAPI" will be defined. 
+# You should prefer to consume this target via target_link_libraries(YOUR_TARGET PRIVATE SuperluminalAPI), rather than by using the above variables directly
