WARNING: Project targetting '>= 0.44.0' but tried to use feature
introduced in '0.50.0': install arg in configure_file

From the documentation:

 "install (added 0.50.0) When true, this generated file is installed
 during the install step, and install_dir must be set and not
 empty. When false, this generated file is not installed regardless of
 the value of install_dir. When omitted it defaults to true when
 install_dir is set and not empty, false otherwise."

The parameter can be omitted because install_dir is set.
