# This module finds the CUSP header files and extracts their version. It
|
|
# sets the following variables.
|
|
#
|
|
# CUSP_INCLUDE_DIR - Include directory for cusp header files. (All header
|
|
# files will actually be in the cusp subdirectory.)
|
|
# CUSP_VERSION - Version of cusp in the form "major.minor.patch".
|
|
#
|
|
# CUSP_FOUND - Indicates whether Cusp has been found
|
