  By not providing "FindEIGEN3.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "EIGEN3", but
  CMake did not find one.

  Could not find a package configuration file provided by "EIGEN3" with any
  of the following names:

    EIGEN3Config.cmake
    eigen3-config.cmake

  Add the installation prefix of "EIGEN3" to CMAKE_PREFIX_PATH or set
  "EIGEN3_DIR" to a directory containing one of the above files.  If "EIGEN3"
  provides a separate development package or SDK, be sure it has been
  installed.
