Eigen Library Installation

1. Download Eigen Library:

   • Download the latest stable release from Eigen's official website.

2. Check CMake Installation:

   • Before proceeding, ensure that CMake is installed on your computer. You can check this by running the following command in your terminal:

     cmake --version
     

3. Installation Steps:

   • Open the terminal and navigate to the directory where you downloaded Eigen.

     cd path/to/eigen
     

   • Create a build directory:

     mkdir build
     cd build
     

   • Run CMake to configure the build:

     cmake ..
     

   • Install Eigen using:

     sudo make install
     

4. Linking the Library:

   • Add the following lines to your CMakeLists.txt file to link the Eigen library:

     find_package (Eigen3 3.3 REQUIRED NO_MODULE)
     target_link_libraries (your_target Eigen3::Eigen)

     Replace your_target with the name of your target in CMakeLists.txt.

Replace path/to/eigen with the actual path to the directory where you downloaded Eigen. After following these steps, Eigen should be successfully installed on your system.
