Replacing autotools

[trgwii]

As mentioned in #9

Consider moving away from autotools. The whole current process is error-prone
and very slow.

In most cases, autotools cannot detect or recognize that source- or
configuration files have been changed, and thus will not rebuild the necessary
objects and binary files.

These last few days I have also read a couple of papers and articles on make,
autotools, and surrounding infrastructure:

• xz backdoor and autotools insanity
• Recursive Make Considered Harmful
• Notes on the M4 Macro Language

I think ideally these projects should adopt cmake, as it has become something of
an industry standard, but I have not really used it myself, and will have to
investigate a bit more.
