CMake Error at CMakeLists.txt:202 (find_package):
  By not providing "FindGoogletest.cmake" in CMAKE_MODULE_PATH this project
  has asked CMake to find a package configuration file provided by
  "Googletest", but CMake did not find one.

  Could not find a package configuration file provided by "Googletest" with
  any of the following names:

    GoogletestConfig.cmake
    googletest-config.cmake

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