CMake Error at CMakeLists.txt:41 (find_package):
  By not providing "Findimu.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "imu", but
  CMake did not find one.

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

    imuConfig.cmake
    imu-config.cmake

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