What's this?

enable_config(config, default=nil) public

Tests for the presence of an --enable-config or --disable-config option. Returns true if the enable option is given, false if the disable option is given, and the default value otherwise.

This can be useful for adding custom definitions, such as debug information.

Example:

if enable_config("debug")
   $defs.push("-DOSSL_DEBUG") unless $defs.include? "-DOSSL_DEBUG"
end
