Wrong debug informations
When compilation of cuda kernels fails due to error in the kernel code, this error message is displayed:
[FATAL] ======>
[FATAL] ======> If your error is related to Optix Library that could not be loaded ============================> DO YOU HAVE A NVIDIA CARD ???
[FATAL] ======> If you have a nvidia card CHECK YOUR DRIVER VERSIONS
This can be misleading in that one may think his OptiX/Cuda installation is wrong, whereas it's caused only be coding errors.
A more thorough check should be done regarding the reasons this message is displayed, so that compilation fails correctly points to their real causes (coding errors or wrong installation).
