trouble building with intel/llvm #12

Closed cperkinsintel closed 3 years ago

cperkinsintel commented 3 years ago

I have the intel/llvm SYCL compiler setup, complete with its environment. It pulls down a LevelZeroLoader, so I was hoping to use that to build ze_tracer rather than a new installation of the Loader.

But despite putting my sycl_workspace/build/include/sycl on CPATH, or CMAKE_REQUIRE_INCLUDES, (and a few other options) the cmake setup for ze_tracer would never complete. It found the level_zero loader library easily enough, but the FindL0Headers macro always failed.

I finally just make sure the required path was on CPATH and then I commented out the body of FindL0Headers in the CMakeLists.txt file. It built fine after that and is running.

Hi Chris, Preferable way to provide libs and headers to cmake is to use CMAKE_LIBRARY_PATH and CMAKE_INCLUDE_PATH variables. I've checked this with intel llvm compiler and it works fine for me:

$ cmake -DCMAKE_LIBRARY_PATH=<sycl_workspace>/build/lib/ -DCMAKE_INCLUDE_PATH=<sycl_workspace>/build/include/sycl/ ..

Please try this out.
