This reverts commit 6ed4aff4.  The
Meson wrap is broken on non-x86, because it unconditionally includes
<cpuid.h> which is an x86 only header.

As per Meson 0.56.0:
 https://mesonbuild.com/Machine-files.html#properties

Not necessary anymore since Meson 0.50.0:
 https://mesonbuild.com/Release-notes-for-0-50-0.html#libdir-defaults-to-lib-when-cross-compiling

Let cmake know that we're cross-crompiling.

Prepare to add some code around the _build() call.

Eliminate conflict with other Project classes.

Allows running the unit tests on Linux.

Got lost in commit 0f56ddb8

The "install_dev" target runs ranlib during installation, and this
can break the Android build.

The script seems to assume package version numbers always end in numeric versions with an optional alpha-suffix. Alas, were it only so simple... Sometimes the package is called fizzbang-1.2.3+release_info in which case the build fails. No more!

This enables the JACK output plugin on Windows, but doesn't link
against libjack64.dll, instead loads the DLL at runtime with
LoadLibrary().  This kludge avoids the extremely fragile JACK shared
memory protocol by using the system's libjack64.dll, without requiring
the same DLL at build time.
