# Some versions of DPC++ compiler pass paths to SYCL headers as user include paths (`-I`) rather

# SYCL headers, such as deprecated warnings, even if warned API is not actually used in the program.
# We expect that this issue will be addressed in the later version of DPC++ compiler. To workaround
# the issue we wrap paths to SYCL headers in `-isystem`.
