I am trying to get value of a variable whose name is defined with another variable.

This is how it is defined, but I am getting error

  - name: output of dictionary - filepath
    debug:
      msg: "override_conf_loc: {{item.group }}|{{item.path}}"
    loop:  "{{override_conf_loc}}"

  - name: set_fact - filepath
    set_fact:
      override_filepath_{{item.group }}: "{{item.group }}|{{item.path}}"
      var_name: "override_filepath_{{item.group }}"
    loop:  "{{override_conf_loc}}"

  - name: debug - filepath - attempt 1
    debug:
      msg: "override_filepath: {{'override_filepath_' +  {{item.group }} }}"
    loop:  "{{override_conf_loc}}"

  - name: debug - filepath- attempt 2
    debug:
      msg: "override_filepath: vars['override_filepath_' +  {{item.group }}]"
    loop:  "{{override_conf_loc}}"

  - name: debug - - attempt 3
    debug:
      msg: "override_filepath: {{var_name }}"
    loop:  "{{override_conf_loc}}"

How can I use the variable value of var_name for every host?
