a string or an array of strings
representing additional paths to search for headers.

=item INC

a C<ExtUtils::MakeMaker>-style space-separated list of
incpaths, each preceded by '-I'.

This can also be supplied on the command-line.

=item ccflags

Extra flags to pass to the compiler.

=item ldflags

Extra flags to pass to the linker.

=item analyze_binary

a callback function that will be invoked in order to perform custom
analysis of the generated binary. The callback arguments are the
library name and the path to the binary just compiled.

It is possible to use this callback, for instance, to inspect the
binary for further dependencies.
