# FindThrust

# This module finds the Thrust header files and extrats their version. It
# sets the following variables.
#
# THRUST_INCLUDE_DIR - Include directory for thrust header files. (All header
# files will actually be in the thrust subdirectory.)
# THRUST_VERSION - Version of thrust in the form "major.minor.patch".
