compile error in linux

[wantyNing]

HI,
I tried to compile this project in linux.
And the G+Smo was compiled successfully, when I try to compile the shapeopt，
cmake ..
the output is below:

root@wanty-VirtualBox:/home/shape1/build# cmake ../shape

but when I try to make，Some errors have occurred

Is it that the version I selected does not match？
Could you please provide some advice?
Thanks a lot!
