CMake Error at CMakeLists.txt:159 (find_package):
  By not providing "FindGMP.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "GMP", but
  CMake did not find one.

  Could not find a package configuration file provided by "GMP" (requested
  version 6.0.0) with any of the following names:

    GMPConfig.cmake
    gmp-config.cmake

  Add the installation prefix of "GMP" to CMAKE_PREFIX_PATH or set "GMP_DIR"
  to a directory containing one of the above files.  If "GMP" provides a
  separate development package or SDK, be sure it has been installed.
