| 13 | # components of libomptarget. These are the dependencies we have: |
| 14 | # |
| 15 | # libelf : required by some targets to handle the ELF files at runtime. |
| 16 | # libffi : required to launch target kernels given function and argument |
| 17 | # pointers. |
| 18 | # CUDA : required to control offloading to NVIDIA GPUs. |
