c++ - CMake error. could not find Eigen3Config.cmake

Question

This is what I have done for my project downloaded from Git: created my_build_dir as master>my_build_dir then ran "cmake .." in the folder my_build_dir

I get the following error.

Could not find a package configuration file provided by "Eigen3" (requested version 3.3) 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.

I am new to cmake and don't have a background in coding and therefore would be glad if someone could explain to me what i need to do with code examples.
