How to get disatnce from one point to Line in 3D space using openGL math library glm?

I have set of points (3D). What i am doing is getting a line that connect first and last point of data set. Then trying to find index of point that has max distance from line. Just to express my problem Attachment 2507.

I wrote a function for that which uses **Eigen** library. Which is as below

Code :

std::vector<Eigen::Vector3f> points; // input set of points
typedef Eigen::ParametrizedLine<float, 3> Line3;
static Line3 start_to_end = Line3::Through(points[0], points.back());
float max_dist_squared = 0.0f;
size_t max_idx = 0;
for (size_t i = 0; i<points.size(); ++i)
{
float dist2 = start_to_end.distance(points[i]);
if (dist2 > max_dist_squared)
{
max_dist_squared = dist2;
max_idx = i;
std::cout << "\n Distance is " << dist2 << " and i " << i << std::endl;
}
}

PROBLEM : I want to write same method using GLM. I mean to ask is any method that help me to find **line** and distance from a point. Or how can i convert above code Using GLM library.
