# - Find OpenShadingLanguage library
|
|
# Find the native OpenShadingLanguage includes and library
|
|
# This module defines
|
|
# OSL_INCLUDE_DIRS, where to find OSL headers, Set when
|
|
# OSL_INCLUDE_DIR is found.
|
|
# OSL_LIBRARIES, libraries to link against to use OSL.
|
|
# OSL_ROOT_DIR, the base directory to search for OSL.
|
|
# This can also be an environment variable.
|
|
# OSL_COMPILER, full path to OSL script compiler.
|
|
# OSL_FOUND, if false, do not try to use OSL.
|
|
# OSL_LIBRARY_VERSION_MAJOR, OSL_LIBRARY_VERSION_MINOR, the major
|
|
# and minor versions of OSL library if found.
