+# Build the host-side CUDA bridge daemon.

+# Kernels are written in CUDA C, compiled to PTX at build time by nvcc, and
+# embedded into the binary by embed_ptx.py, so cuda_bridge needs only the
+# driver's libcuda at runtime. kernels_ptx.h is a generated file; if it is
+# already present the build works without nvcc.
