Can not finish building properly, help please

[Tetsujinfr]

I have the below error at bulding. There are some CMake warnings but I cannot figure out if the build error is due to those warnings and what they mean neiher.
Can you help me?
(I am building everything under colab, CUDA version is 10.1 and CuDNN 7)

%cd /content/DeepFactors/
! mkdir build
% cd build

This looks like an issue specific to trying to build it in colab. It's hard for me to comment on what is going on here as I do not know the configuration of the OS there.

It might be that they do not have the right GL installed.
