png driver not loaded (Windows)

[Linda R]

Okay.  Everytime I think I am getting closer I realize I may never get this to work.  This has been the most painful thing I have ever experienced. 

I cannot get the wxwidgets plot window to work so I have decided to switch to just doing a plplot and saving it as an image.

It can find the device drivers now it just cannot load them.  It fails on this line. 

// If it still isn't loaded, then we're doomed.
    if ( !driver->dlhand )
    {

PS.  BTW.  Building PLPLOT is a work in progress.  Here is my current batch file. 

Pull the latest source to here:

C:\dev\sources\plplot

From here:

https://plplot.svn.sourceforge.net/svnroot/plplot/trunk

and here

You also need to specify the following in the cmake command.

-DENABLE_DYNDRIVERS=OFF

It is now saving to png.
