# - Find GMP/MPIR libraries and headers
# This module defines the following variables:
#
# GMP_FOUND - true if GMP/MPIR was found
# GMP_INCLUDE_DIRS - include search path
# GMP_LIBRARIES - libraries to link with
# GMP_LIBRARY_DLL - library DLL to install. Only available on WIN32.
# GMP_LIBRARIES_DIR - the directory the library we link with is found in.
