+# Input variables:
+# 
+# - Eigen_ROOT_DIR (optional): When specified, header files and libraries
+#   will be searched for in `${Eigen_ROOT_DIR}/include` and
+#   `${Eigen_ROOT_DIR}/libs` respectively, and the default CMake search order
+#   will be ignored. When unspecified, the default CMake search order is used.
+#   This variable can be specified either as a CMake or environment variable.
+#   If both are set, preference is given to the CMake variable.
+#   Use this variable for finding packages installed in a nonstandard location,
+#   or for enforcing that one of multiple package installations is picked up.

+# Cache variables (not intended to be used in CMakeLists.txt files)

+# - Eigen_FOUND: Boolean that indicates if the package was found
+# - Eigen_INCLUDE_DIRS: Paths to the necessary header files
+# - Eigen_VERSION: Version of Eigen library found
+# - Eigen_DEFINITIONS: Definitions to be passed on behalf of eigen
+# 
+# 
+# Example usage:
