So, as "luck" would have it, I was spinning up fltk on a Win11 box for
some tests... So I used MSYS2/mingw64, here's some results and
notes...

Uh - that's unexpected... What list do you get if you do a "cmake -G"
with no option set? It *should* print a long list (well, about 60
lines on my set-up) of all the generators it knows about.

The "interesting" ones for Msys use are:

MSYS Makefiles               = Generates MSYS makefiles.
MinGW Makefiles              = Generates a make file for use with
Unix Makefiles                  = Generates standard UNIX makefiles.

All of which I have tried, at one time or another, and as best I can
tell they work "about the same" for my configurations.

This time around I opted for MSYS Makefiles; here's the foot of my
history buffer after the build, so all can see what was done:


git clone https://github.com/fltk/fltk.git fltk-1.4
cd fltk-1.4/
mkdir build-64
cmake -G
cd build-64/
cmake -G "MSYS Makefiles" -D 'CMAKE_BUILD_TYPE=Release'
-DCMAKE_SYSTEM_NAME="Windows" -DOPTION_USE_SYSTEM_ZLIB=OFF
-DOPTION_USE_SYSTEM_LIBJPEG=OFF -DOPTION_USE_SYSTEM_LIBPNG=OFF ..
make -j2

And that Just Worked.

As is traditional now, at the end of the build I remembered I had
forgotten (once again) to enable GLEW and the building of the
examples, so I fired up cmake-gui and turned on GLEW and the examples,
regenerated, and rebuilt. Still OK.
