I am building XGBoost with GPU support on Ubuntu 18.04 following the installation guide. At the stage cmake .. -DUSE_CUDA=ON it fails with make[1]: execvp: /usr/local/cuda/bin: Permission denied.
The full output is below.

Check if you are running the command as sudo. Or else check the file permissions. Run chmod +x /usr/local/cuda/bin to get the executables access.
