A plugin for Eigen3 to allow the user of C++11 initializer lists.

#include <iostream>
#include <Eigen/Dense>

using namespace Eigen;

int main()
{
	// Init a fixed size 3x3 matrix
	Matrix3d m3 {{1.2,2.2,3.3},{4.2,2.5,6.3},{7.2,8.2,9.3}};
	std::cout << "\nm3:\n" << m3 << std::endl;


	// Initialize a variable length Matrix to 2x2
	MatrixXd mY {{1.2,2.2},{3.2,4.5}};
	std::cout << "\nmY:\n" << mY << std::endl;

	// Initialize a variable length Matrix (Vector) to 9x1
	// 2D Matrices are initialized column-wise
	MatrixXd mX {1.2,2.2,3.3, 4.2,2.5,6.3, 7.2,8.2,9.3};
	std::cout << "\nmX:\n" << mX << std::endl;

	// Init a 3 element vector
	Vector3d v3  {1,3,3};
	std::cout << "\nv3:\n" << v3 << std::endl;
}

The key line to add to your CMakeLists.txt file is:
