+This will compile the jack standalone version, and LV2, VST2, and VST3 versions. It ought to be possible to also compile VST/VST3 and AU versions for Windows and Mac OS but these have not yet been tested. The github runner currently reports them as successfully built.

+Windows versions may be built with:
+
+    ( cd dpf; make clean ) # note the brackets
+    make clean
+    make mingw64
+    # or make mingw32 if you want 32-bit
+
+This appears to work, in limited testing.
