Those are reason why I like small "single" file libraries in C and C++ (one header, one source file): you know where the source code is, reviewing it is relatively painless, and adding it to your project is dead easy. Yet I have seen people ignoring the benefits of a 2K lines dependency (in a single compilation unit), over an otherwise equivalent 20K lines dependency (in 100 compilation units) that requires the autotools. (The disadvantages of a particular lightweight dependency is a separate topic.) You want your modules do be deep: minimum interface for maximum functionality. Dividing the size of an interface by 10 for the same functionality is a pretty sweet deal in most cases. In my opinion, that deal is often underrated.
