I performed the best by setting the LD_LIBRARY_PATH to include lib/csa
and src, which are the locations of the csa and plplot DLL's.  I
configured plplot with the command

cmake -DCMAKE_INSTALL_PREFIX=install -DCMAKE_VERBOSE_MAKEFILE=ON
-DBUILD_TEST=ON -DENABLE_DYNDRIVERS=ON -DENABLE_tk=OFF -DENABLE_tcl=OFF
../plplot-pure

where plplot-pure is a fresh copy of 7989.  The build directory was
empty.  The make command failed when it attempted to build the drivers
with the following error

cd /opt/build/cygwin-no-ivf/drivers && ./get-drv-info.exe hpgl >
/opt/build/cygwin-no-ivf/drivers/hpgl.rc
make[2]: *** [drivers/hpgl.rc] Error 53

If I type type the following command

strace ./get-drv-info.exe hpgl

I get a dialog box stating that libplplotd-9.3.0.dll was not found even
though it can be found on the LD_LIBRARY_PATH.  I also added the src
directory to the PATH and get-drv-info was able to work.  I then cleaned
the build directory and was able to successfully build with dyndrivers
enabled.
