CMake check if CUDA environment exists without find_package

As stated here https://cmake.org/cmake/help/latest/module/FindCUDA.html

find_package(CUDA)

is a deprecated way to use CUDA in CXX project. We have to use

project(MY_PROJECT LANGUAGES CUDA CXX)

but how can I detect whether the current platform supports CUDA. The goal is to exclude some targets from build if CUDA is not installed.

Just found a solution thanks to a comment posted on the question referring to this Stack Overflow answer, and in turn this piece of documentation.

Here is a code snippet :

cmake_minimum_required(VERSION 3.8)
include(CheckLanguage)

project(my_project)

check_language(CUDA)
if (CMAKE_CUDA_COMPILER)
        message(STATUS "CUDA is OK")
else()
        message(STATUS "No CUDA")
endif()
