You built with BUILD_GUI=TRUE and you have no GUI and no error messages?
no I did not feel comfortable editing the make file as smooth suggested as he said he had not done that himself and seemed uncertain:
"It's not something I've done but looking at the CMakeLists.txt file I'd guess that going into the Makefile and changing
cmake -D CMAKE_BUILD_TYPE=Release
to
cmake -D CMAKE_BUILD_TYPE=Release -D BUILD_GUI=TRUE
Then make as usual
or if not that, then something close to it."
The above instructions look great for someone who is more experienced than I am. I have never edited a makefile.
I am new to Linux and did not want to experiment
Then you shouldn't have said:
If you read all of my comments you will see that currently there is no error message and I appear to have all dependencies. The problem is that I followed all the instructions and there is no GUI
