Could NOT find IntelSycl (missing: IntelSycl_SYCL_LIBRARY

[yurivict]

cmake first finds IntelSycl and then fails:

[oleksandr-pavlyk]

@yurivict Thank you for the report. It appears that our cmake script is failing to locate libraries libsycl.so and libOpenCL.so in the folder SYCL_LIBRARY_DIR as set by find_package(IntelDPCPP REQUIRED).

The SYCL_LIBRARY_DIR is found as follows:

  find_file(SYCL_LIBRARY_DIR
    NAMES
      lib lib64
    HINTS
      ${SYCL_PACKAGE_DIR} $ENV{SYCL_LIBRARY_DIR_HINT}
    NO_DEFAULT_PATH
      )

Where the SYCL_PACKAGE_DIR is the parent folder of the bin/ folder containing the compiler executable.

The expected compiler layout is aligned with that of oneAPI DPC++, or open-source SYCL bundle downloadable from https://github.com/intel/llvm/releases

If the opensycl layout is different, perhaps use SYCL_LIBRARY_DIR_HINT environment variable to assist cmake in locating the library directory.

Please do let us know if you are running into additional issues.
