Hi Greg:

Thanks for that report of your qhull find troubles on the
MinGW-w64/MSYS platform.  The rest of this is addressed to Arjen (or
anyone else here with interest in the important qhull component of our
plgriddata API on that platform) because I think he is going to
encounter those same troubles soon.

@Arjen:

Your latest latest (2017-08-17) successful test of the mingw64 version
of MinGW-w64/MSYS2 shows the following qhull-related find results:

-- Found QHULL: D:/mingw64-2/mingw64/include 
-- QHULL_INCLUDE_DIRS = D:/mingw64-2/mingw64/include
-- HAS_LIBQHULL_INCLUDE = OFF
-- QHULL_LIBRARIES = D:/mingw64-2/mingw64/lib/libqhull.dll.a
-- QHULL_RPATH =

So all *was* well in that case.

However, it appears there is qhull trouble ahead for you just like
Greg has encountered.  Note that the above import library and
corresponding dll is available for both
<http://repo.msys2.org/mingw/x86_64/mingw-w64-x86_64-qhull-git-r113.60d5581-3-any.pkg.tar.xz>
and
<http://repo.msys2.org/mingw/x86_64/mingw-w64-x86_64-qhull-git-r151.5bbc756-1-any.pkg.tar.xz>,
but they are not available for the latest version,
<http://repo.msys2.org/mingw/x86_64/mingw-w64-x86_64-qhull-git-r157.f0bd8ce-1-any.pkg.tar.xz>.
and the corresponding latest 32-bit version, 
<http://repo.msys2.org/mingw/i686/mingw-w64-i686-qhull-git-r157.f0bd8ce-1-any.pkg.tar.xz>
that Greg used.  So when you update to that latest 64-bit version of
the qhull library for MinGW-w64/MSYS2 I assume you will run into the
same issue that Greg has encountered, and when that occurs you should
follow up with an error report to the MSYS2 list concerning that
missing import library and dll situation for their latest qhull
package.
