Duh ! It's actually 'mingw32-make.exe' that I need .... and I didn't have it 
installed  - even though it was going to be needed to run the very next 
command.
Sorry, I'm used to building libraries with MinGW by running configure and 
make in the MSYS shell. MSYS, of course, has its own make utility, so I 
haven't had any need for mingw32-make until now. Some of my MinGW 
installations do have mingw32-make installed, but not the installation I was 
using (of which I was unaware).

Having installed mingw32-make, I then decided to try first for static libs 
(which I generally prefer), so I ran:

cmake -G "MinGW 
Makefiles" -DCMAKE_INSTALL_PREFIX=install -DBUILD_SHARED_LIBS=OFF ..

There's some messages in the output about various libraries not being found, 
and other things. I'll have to go back and have a closer look at them.
Runnning 'mingw32-make' and 'mingw32-make install' worked fine.

I then tried a re-build, adding the '-DBUILD_TEST=ON' option.

The c and c++ examples built ok (and the ones I've tried work fine), but 
there's a linking problem with the f77 examples that kills the show:

I'm not greatly fussed as to which I use - and I'll probably experiment with 
both. I'll also have to make sure that I can build dynamic libs ok, that the 
MinGW ports of gcc-4.x.x also work (I was using gcc-3.4.5), and I'll be 
interested to see how things go when I try using a 64-bit build of MinGW. 
So, maybe expect some more mail from me on this list in the near future :-)

Thanks for the reply.

Cheers,
