have_framework(fw, &b)

public

Returns whether or not the given framework can be found on your system. If found, a macro is passed as a preprocessor constant to the compiler using the framework name, in uppercase, prepended with ‘HAVE_FRAMEWORK_’.

For example, if have_framework(‘Ruby’) returned true, then the HAVE_FRAMEWORK_RUBY preprocessor macro would be passed to the compiler.
