You can read the file auto/lib/libxslt/conf to get an idea of what nginx
is testing for.

Do you have, for example, the file libxml/parser.h somewhere on your
system?

Did you install the library packages for running programs with; or did
you install the development packages to allow programs be built against
the libraries?

Possibly you want packages with "-dev" or "-devel" in the name, if you
don't already have them.

The content of https://packages.msys2.org/package/libxml2-devel and
https://packages.msys2.org/package/libxslt-devel makes it look like it
should Just Work, if both are installed.

If that doesn't happen, then probably auto/lib/libxslt/conf can be
adjusted to let it happen.

Good luck with it,
