环境

• Intel One API 2023.2
• CMake 3.27.7
• Visual Studio 2022 Community (with C++ desktop)

样例

程序代码

1 #include <iostream>
2 
3 int main()
4 {
5     std::cout << "Hello, CMake!" << std::endl;
6     std::cin.get();
7     return 0;
8 }

MakeList

 1 cmake_minimum_required(VERSION 3.23)
 2 
 3 # Heroius: set() function should be called before project() to take effect, otherwise default compilers will be used.
 4 
 5 # specify Intel oneAPI compiler
 6 # Heroius: use '/' instead of '\\' in file paths to avoid incorrect mutiple letter escaping.
 7 # Heroius: however these compiler flags seem only placeholders and not used at all.
 8 set(CMAKE_C_COMPILER "C:/Program Files (x86)/Intel/oneAPI/compiler/latest/windows/bin/dpcpp.exe" CACHE STRING "" FORCE)
 9 set(CMAKE_CXX_COMPILER "C:/Program Files (x86)/Intel/oneAPI/compiler/latest/windows/bin/dpcpp.exe" CACHE STRING "" FORCE)
10 
11 # Heroius: the toolchain string determines used c++ compiler, but leaves c compiler unset.
12 set(CMAKE_GENERATOR_TOOLSET "Intel(R) oneAPI DPC++ Compiler 2023")
13 
14 # Heroius: skip c compiler checking, since c compiler is just a mock.
15 set(CMAKE_C_COMPILER_WORKS TRUE)
16 
17 # Set the project name and version
18 # Heroius: move project() instruction here to make flags take effect.
19 project(HelloCMake)
20 
21 # look for Intel oneAPI CMake toolchain files
22 # Heroius: strange error occurs if c compiler checking is not skipped.
23 find_package(IntelSYCL REQUIRED)
24 
25 # Add the executable
26 add_executable(HelloCMake HelloCMake.cpp)
27 
28 # Heroius: there should be a way that can include sycl libs to generation path, so that the app can run itself.
29 # add_sycl_to_target(TARGET HelloCMake SOURCES HelloCMake.cpp)
30 
31 set_target_properties(HelloCMake PROPERTIES
32     RUNTIME_OUTPUT_DIRECTORY_DEBUG ${CMAKE_BINARY_DIR}/bin
33     RUNTIME_OUTPUT_DIRECTORY_RELEASE ${CMAKE_BINARY_DIR}/bin
34     # ... add other configurations if needed
35 )
36 
37 # Set executable path

Configure脚本

 1 :: 设置 OPENCV_ROOT 环境变量
 2 Set OPENCV_ROOT=C:\OpenCV\Build
 3 :: 如果存在 Build，删除
 4 if exist Build rd /S /Q Build 
 5 :: 如果不存在 Build，创建
 6 if not exist Build md Build
 7 
 8 Call "C:\Program Files (x86)\Intel\oneAPI\setvars.bat" intel64 vs2022
 9 
10 :: 当前文件夹为 Source，子文件夹 .\Build 为构建目录
11 cmake -S . -B .\Build 

编译脚本

1 :: 进入构建目录
2 cd Build
3 :: 构建，项目文件在当前目录
4 cmake --build .
5 pause

运行脚本

1 @ECHO OFF
2 
3 :: 加载ONEAPI环境，使得引用库在运行环境可见；将加载过程的输出重定向隐藏
4 Call "C:\Program Files (x86)\Intel\oneAPI\setvars.bat" intel64 vs2022 >NUL 2>&1
5 
6 cd ./build/bin/
7 
8 hellocmake.exe

注意事项

• 要使用Intel One API，需要CMake版本不低于3.23
• CMakeList中，在调用project()之前设置好编译器参数
• Intel One API 2023.2 未提供专用于C的编译器，因此须跳过CMake中的C编译器检查
• 实际确定编译器的是CMAKE_GENERATOR_TOOLSET变量，但是各编译器变量的设置也不能跳过
• CMakeList中的路径变量，使用反斜杠作为路径分隔符，以避免多次转义导致的错误
• 使用find_package(IntelSYCL REQUIRED)添加对Intel One API的引用
• 生成的程序需要在One API环境运行，因在生成目录中没有复制必要的库文件（此问题或有其他解决方案，欢迎留言指正）
