AFAIK, oneAPI compiler is identified as "Clang" compiler (at least for 2021.1).
CMAKE_CXX_COMPILER=/opt/intel/oneapi/compiler/2021.1.1/linux/bin/clang++
CMAKE_CXX_COMPILER=/opt/intel/oneapi/compiler/2021.1.1/linux/bin/clang++
CMAKE_CXX_COMPILER_ABI=ELF
CMAKE_CXX_COMPILER_AR=/opt/intel/oneapi/compiler/2021.1.1/linux/bin/llvm-ar
CMAKE_CXX_COMPILER_AR=/opt/intel/oneapi/compiler/2021.1.1/linux/bin/llvm-ar

CMAKE_CXX_COMPILER_ARG1=
CMAKE_CXX_COMPILER_ENV_VAR=CXX
CMAKE_CXX_COMPILER_FRONTEND_VARIANT=GNU
CMAKE_CXX_COMPILER_ID=Clang <<<====== here
Intel Compiler (from "Intel(R) Parallel Studio XE" product) is a different product.

There are two compilers in oneAPI, I used icc which identifies as "Intel" (I think it is called classic in terms of oneAPI package):
-- C++ Compiler: /opt/intel/oneapi/compiler/2021.2.0/linux/bin/intel64/icc (ver 20.2.2.20210228)
