6. Build and install packages for dependencies (...)

... I get an error when making stk ('pkgname can not start with a -')

8. (...) manually set the following CMake variables:

Some of the above comments relate to errors, and I wonder if they are
serious errors (related to the build error I got?). Other comments
(would be helpful) is just suggestions that might make it easier for
people that do these kinds of tasks more seldom and do not remember
the details (e.g. me)

Michael's recent changes have complicated the build (I replied about
the CURL and musicxml changes in a previous email). The advice to
change environment variables I'm not sure about, but I think that's
just saying be careful in case you have done something like put a
different version of build tools on your system's path.  Anyways, for
the time being, you can try using this my-build.sh script by placing
it in the mingw64 folder and calling it instead of build.sh. It will
execute build.sh with some additional flags for CMake.  Adjust the
paths in my-build.sh if necessary. Also for building packages, try
using makepkg-mingw and not makepkg. For musicxml and others, you can
use "makepkg-mingw -s" which should first install dependencies before
trying to build.

Thanks for this, Steven.
It would be very nice to have the suggestions of using makepkg-mingw
instead of makepkg in the readme, preferably as an example on how to
build and install one of the packages. These are details that can save
a newbie hours :-)
Should I make an issue (or separate issues for each suggestion
perhaps) for my readme suggestions?

btw. it seems that I could finally build by disabling curl and a few
other things. So it might be within reach to get the full build
working. I'm just fulltime occupied with a concert production this
week, so just very brief moments to dive into this.

One question about the more complicated build on windows (Mike?):
Are all these changes (the recent changes to the build) necessary to
build the exact same Csound version as we have on Linux and OSX, or
are there extra bells and whistles on the windows version that
complicates things? It would be nice if the standard build was
configured the same on all three major systems in my opinion.

makepkg-mingw is already mentioned in the README.md.  The big
difference between Windows and other platforms is that 3rd-party
libraries are statically linked into the build artifacts rather than
dynamically linked.  This was instigated by Rory a while back to deal
with issues of embedding Csound into other applications (i.e., Cabbage
had issues when used in certain DAWs, csound~ had issues with pthread
conflicts).  I have not looked into the Windows installer and how it
differs from other platforms.

The use of static libraries was working with mingw64, but Michael
added libcurl and musicxml as dynamically-linked library dependencies.
The reason for this is that the two libraries don't appear to have
static library build options. Musicxml is related to CsoundAC, which
shouldn't be as much a concern, but libcurl and its use in libcsound
could potentially re-introduce problems again when embedded within
apps.
