This is my build file.

project('meson_prac', 'cpp',
  version : '0.1',
  default_options : ['warning_level=3',
                     'cpp_std=c++17'])


sfml_proj = subproject('sfml')
sfml_dep = sfml_proj.get_variable('sfml_dep')

exe = executable('meson_prac', 'meson_prac.cpp',

  install : true)

test('basic', exe)
