Within the build tree, it is easy enough for the routines to find them, but outside you may need to set the environment variable PLPLOT_DRV_DIR.

Hi Arjen and Walt:

@Arjen: Just to clarify, I haven't tried extensive testing of the
"MinGW Makefiles" generator case, and I know there are continuing
PLplot problems with blanks in pathnames.  So for either of those
cases, the above historical workarounds (or some other workaround)
might be needed for Windows.  And also for 5.10.0, the "MSYS
Makefiles" case with no blanks in pathnames passed some limited build
tree tests but not install-tree tests.

However, I just double-checked and for the git master branch (at least
for commit id 3e817e8 on that branch that came after the release of
5.10.0,see details at the bottom of
<https://sourceforge.net/p/plplot/wiki/Testing_PLplot/>), I finally
got all comprehensive testing to work without issues for the the "MSYS
Makefiles" case with no blanks in pathnames case.

@Walt: I rarely do comprehensive testing on my Wine platform because
it is an incredibly slow version of Windows (comprehensive tests take
a couple of days of cpu time rather than a couple of hours). However,
I don't anticipate that we have introduced any Windows build or test
issue on the master branch since the last time I did that
comprehensive test. Therefore, I suggest you use the latest git master
branch version of PLplot and the "MinGW MSYS" generator with no blanks
in any pathname to see if you can replicate the good Windows result I
had for that case for an earlier master branch version.
