title: Run configure in gyp file
body: <p>Suppose I have a node module which is essentially a wrapper around some standard C library using autotools. So the library by itself would be installed using <code>./configure</code> and <code>make</code> and perhaps <code>make install</code>. The wrapper code is just a few files, and can be handled by gyp. But how can I handle the dependency? How can I instruct gyp that I want to build the autotooled library before I compile my code? Or is that not possible because autotools can't be expected to run on Windows? If I can't run <code>configure</code>, is there some gyp way to do similar things, in particular to detect which functions are availabel and which are not?</p>
