Build Windows releases with openssl; automate external libraries
External libraries for Windows are now built automatically in the
qpdf/external-libs repository and include openssl in addition to zlib
and jpeg. Use these, and update the Windows build to build with the
openssl crypto provider by default. We leave the native crypto
provider enabled in case there is a problem with openssl and also to
continue to exercise that code.

-In order to build qpdf, you must have a copy of `zlib` and the `jpeg` library. The easy way to get it is to download the external libs from the qpdf download area. There are packages called `external-libs-bin.zip` and `external-libs-src.zip`. If you are building with MSVC 2015 or MINGW with MSYS2, you can just extract the `qpdf-external-libs-bin.zip` zip file into the top-level qpdf source tree. Note that you need the 2017-08-21 version (at least) to build qpdf 7.0 or greater since this includes jpeg. Passing `--enable-external-libs` to `./configure` (which is done automatically if you follow the instructions below) is sufficient to find them.
+In order to build qpdf, you must have a copy of `zlib` and the `jpeg` library. You can download [prebuilt static external libraries from the qpdf/external-libs github repository](https://github.com/qpdf/external-libs/releases). These include `zlib`, `jpeg`, and `openssl` libraries. There are packages called `external-libs-bin.zip` and `external-libs-src.zip`. If you are building with a recent MSVC or MINGW with MSYS2, you can just extract the `qpdf-external-libs-bin.zip` zip file into the top-level qpdf source tree. Note that you need the 2020-10-24 version (at least) to build qpdf 10.0.2 or greater since this includes openssl. Passing `--enable-external-libs` to `./configure` (which is done automatically if you follow the instructions below) is sufficient to find them.
You can also obtain `zlib` and `jpeg` directly on your own and install them. If you are using mingw, you can just set `CPPFLAGS`, `LDFLAGS`, and `LIBS` when you run ./configure so that it can find the header files and libraries. If you are building with MSVC and you want to do this, it probably won't work because `./configure` doesn't know how to interpret `LDFLAGS` and `LIBS` properly for MSVC (though qpdf's own build system does). In this case, you can probably get away with cheating by passing `--enable-external-libs` to `./configure` and then just editing `CPPFLAGS`, `LDFLAGS`, `LIBS` in the generated autoconf.mk file. Note that you should use UNIX-like syntax (`-I`, `-L`, `-l`) even though this is not what cl takes on the command line. qpdf's build rules will fix it.
-You can also download `qpdf-external-libs-src.zip` and follow the instructions in the README.txt there for how to build external libs.
+External libraries are built using GitHub Actions from the [qpdf/external-libs](https://github.com/qpdf/external-libs) repository.
