Thank you for the notes:

My application only used OpenGL as an unnecessary side offering, so after
removing all the OpenGL references, I was able to get the application to
run.

I did end up with the following error after trying to compile:
  Error: Can't call the assembler, error -1 switching to external assembling
I solved that by reading some other postings where you suggested to
reduce the GPU memory which I did as follows:
  Raspberry menu ->
   Raspberry Pi Configuration ->
Performance ->
 GPU Memory = 32 (from 64).


I'd still like to get opengl working with my application on the RPi one
day, but it is not critical for me.


Thanks,
Anthony
