https://cmake.org/cmake/help/latest/release/3.25.html says:
"On Windows, when targeting the MSVC ABI, the find_library() command now
accepts .a file names after first considering .lib. This is symmetric
with existing behavior when targeting the GNU ABI, in which the command
accepts .lib file names after first considering .a."
If "MSVC" is defined, only search for libsmi-2. This keeps us from finding
libsmi.a. Set NO_SYSTEM_ENVIRONMENT_PATH when we're searching for zlib. This
keeps us from finding Strawberry Perl's version.
Some SpanDSP builds link with LibTIFF, but our Windows version doesn't.
Asciidoctor lets us generate multiple documents at once, so do so for
our man pages. If we're using AsciidoctorJ this minimizes the number
of JVM instances we have to spin up. This reduces the build time on my
Windows VM here quite a bit, and will hopefully do so on the CI builders.
Add a .editorconfig file in cmake/modules.
