I feel really uncomfortable while reading this question. Because I think it is not the right way to run a launch file. Launch files are designed to run nodes (C++/python). Anyways, I found a similar question #q341272

@ravijoshi I think you should make your comment the answer.

@ROS_Practicer If you try this, you're also going to have to make sure that the setup.bash environment variables are all set properly.

Below is the answer:

#include <cstdlib>
...
std::system("roslaunch your_package your_node");

Finally, as @Mike Scheutzow said that ROS environment variables must be set up correctly before running the above code. Therefore, please source the setup.bash
