# Locate Castor3D library
# This module defines :
#  	Castor3D_LIBRARIES :	The library to link against
#  	Castor3D_FOUND :		If false, do not try to link to Castor3D
#  	Castor3D_INCLUDE_DIR :	Where to find headers.
#	Castor3D_LIBRARY_DIR :	Where to find the library
# You just have to set Castor3D_ROOT_DIR in your CMakeCache.txt if it is not found.
# If Castor3D was built in a special folder, you can specify it in Castor3D_LIBRARY_DIR
