# - Find GMP library
# Find the native GMP includes and library
# This module defines
# GMP_INCLUDE_DIRS, where to find gmp.h, Set when
# GMP_INCLUDE_DIR is found.
# GMP_LIBRARIES, libraries to link against to use GMP.
# GMP_ROOT_DIR, The base directory to search for GMP.
# This can also be an environment variable.
# GMP_FOUND, If false, do not try to use GMP.
#
# also defined, but not for general use are
# GMP_LIBRARY, where to find the GMP library.
