# Try to detect in the system several dependencies required by the different
# components of libomptarget. These are the dependencies we have:
#
# libelf : required by some targets to handle the ELF files at runtime.
# libffi : required to launch target kernels given function and argument
# pointers.
# CUDA : required to control offloading to NVIDIA GPUs.
