@invisibleroads can you try this fix? thanks!

@kashif

I can confirm that your fix now runs successfully on ec2.

However, the cmake modifications, while successful on ec2, seem to fail for older graphics cards. I created a new issue here #12

Makes me wonder what was wrong with the original name of the .so file!

@dnouri yes it was my fault, I should not have changed it, I was looking at the __import__() method and trying to get Cmake to generate the shared file name without the "lib" prefix and got rid of the underscore in the name without realising that there was a clash... 😊 Thanks for merging!
