CLion - CUDA Syntax - "Use of undeclared identifier cudaConfigureCall"

I have a simple HelloWorld CUDA application that builds and runs correctly. I'm using CLion 2020.2 which supports CUDA syntax however I'm getting a false error "Use of undeclared identifier cudaConfigureCall". According to this JetBrains site CLion should support this syntax.

I'm building this CMake project on Ubuntu 20.04 using CUDA 11.0 compiled with nvcc, gcc-8.0 and g++-8.0

Any thoughts?

Here's my CMakeLists.txt and Toolchain settings

cmake_minimum_required(VERSION 3.16)
project(LinuxCudaTest CUDA CXX)

set(CMAKE_CUDA_STANDARD 14)

add_executable(LinuxCudaTest main.cu)

set_target_properties(
        LinuxCudaTest
        PROPERTIES
        CUDA_SEPARABLE_COMPILATION ON)
