# Find the native OpenSubdiv includes and library

# OPENSUBDIV_INCLUDE_DIRS, where to find OpenSubdiv headers, Set when

# OPENSUBDIV_INCLUDE_DIR is found.
|
|
# OPENSUBDIV_LIBRARIES, libraries to link against to use OpenSubdiv.
|
|
# OPENSUBDIV_ROOT_DIR, the base directory to search for OpenSubdiv.
|
|
# This can also be an environment variable.
|

# OPENSUBDIV_FOUND, if false, do not try to use OpenSubdiv.
