 QPDF's build system, inspired by [abuild](https://www.qbilt.org/abuild), can optionally use its own built-in rules rather than using libtool and obeying the compiler specified with configure.  This can be enabled by passing `--with-buildrules=buildrules` where buildrules corresponds to one of the `.mk` files (other than `rules.mk`) in the make directory. This should never be necessary on a UNIX system, but may be necessary on a Windows system.  See [README-windows.md](README-windows.md) for details.

 The software library is just `libqpdf`, and all the header files are in the `qpdf` subdirectories of `include` and `libqpdf`. If you link statically with `-lqpdf`, then you will also need to link with `-lz` and `-ljpeg`. The shared qpdf library is linked with `-lz` and `-ljpeg`, none of qpdf's public header files directly include files from `libz`, and only `Pl_DCT.hh` includes files from `libjpeg`, so for most cases, qpdf's development files are self contained. If you need to use `Pl_DCT` in your application code, you will need to have the header files for some libjpeg distribution in your include path.
