    build: Use generators placeholders
    
    Functions derived from generators as `configure_file`,
    `custom_target` and `i18n.merge_file` can use placeholders like
    `@BASENAME@` that removes the extension from the input filename
    string.
    
    The output string has been replaced by this placeholder that
    allows in some cases the use of less variables.
