Should be something along these lines:

#include <boost/geometry/srs/epsg.hpp>
#include <boost/geometry/srs/projection.hpp>

boost::geometry::srs::projection<> prj = boost::geometry::srs::epsg(3857);
boost::geometry::point_xy<double,  epsg<2040>> my_point(0, 0);

Also, search through the source code of the Boost.Geometry tests
for more details about how `epsg` and `projection` can be used.

Best regards,
