Embree sycl cmake

[peizhao]

Hi,

I try to build a cycle-based Embree application with Cmake as attached below:

cmake_minimum_required(VERSION 3.22.1)

set(CMAKE_CXX_COMPILER icpx)

set(CMAKE_C_COMPILER icx)

set(EMBREE_SYCL_SUPPORT ON)

project(HELLOEMBREE)

set(embree_DIR /mnt/d/embree-4.1.0.x86_64.linux/lib/cmake/embree-4.1.0/)

set(TBB_DIR /mnt/d/oneapi-tbb-2021.2.0/lib/cmake/tbb/)

FIND_PACKAGE(IntelSYCL REQUIRED)

FIND_PACKAGE(embree 4 REQUIRED)

add_executable(HELLOEMBREE embreeTest.cpp)

TARGET_LINK_LIBRARIES(HELLOEMBREE embree)

add_sycl_to_target(

    TARGET HELLOEMBREE

    SOURCES embreeTest.cpp

  )

While the code I was running was one of the examples codes online

embreeTest.cpp 

After Cmake generates the make file in the build directory, I try to build the code using make command the following error occurs:

/mnt/d/Embree_helloWorld/embreeTest.cpp:108:22: error: use of undeclared identifier 'rtcNewSYCLDevice'
RTCDevice device = rtcNewSYCLDevice(sycl_context, "");
^
/mnt/d/Embree_helloWorld/embreeTest.cpp:109:3: error: use of undeclared identifier 'rtcSetDeviceSYCLDevice'
rtcSetDeviceSYCLDevice(device,sycl_device);
^
/mnt/d/Embree_helloWorld/embreeTest.cpp:303:32: error: use of undeclared identifier 'rtcSYCLDeviceSelector'
sycl_device = sycl::device(rtcSYCLDeviceSelector);
^
/mnt/d/Embree_helloWorld/embreeTest.cpp:306:5: error: use of undeclared identifier 'embree'
embree::printAllSYCLDevices();
^
4 errors generated.

gmake[1]: *** [CMakeFiles/Makefile2:83: CMakeFiles/HELLOEMBREE.dir/all] Error 2
gmake: *** [Makefile:91: all] Error 2
