Use icx from cmake in VisualStudio 2022 (add into CMakePresets.json)

[Daniel_D]

Hi,

I try to use the Intel icx compiler for a cmake based project in Visual Studio. To use it there are two steps required if I understood the process correctly from this guide:

 Automate the setvars.bat Script with Microsoft Visual Studio* (intel.com)
- modify the CMakePreset.json
- Add SETVARS_CONFIG environment variable pointing to the oneAPI setvars.bat file

here is what I did:

Changes in CMakePresets.json:
{
"name": "windows-base",
"hidden": true,
"generator": "Ninja",
"binaryDir": "${sourceDir}/out/build/${presetName}",
"installDir": "${sourceDir}/out/install/${presetName}",
"cacheVariables": {
"CMAKE_C_COMPILER": "icx-cl",
"CMAKE_CXX_COMPILER": "icx-cl"
},
"vendor": {
"microsoft.com/VisualStudioSettings/CMake/1.0": {
"intelliSenseMode": "windows-clang-x64"
}
},
"condition": {
"type": "equals",
"lhs": "${hostSystemName}",
"rhs": "Windows"
}
}

Add the SETVARS_CONFIG var:

I check the setvars.bat file in the location and verified that "icx-cl --version" works.

(Need to use a screenshot since i always get an error sending this message as text:

Note: there is not a single ampersand in this message - maybe a bit more AI wouldn't hurt!

This seems to be ok. If I now start VS and try to compile my project with cmake I get:

1> Working directory: W:/Libraries(CMAKE)/out/build/x64-debug
1> [CMake] -- The CXX compiler identification is unknown
1> [CMake] CMake Error at W:\Libraries(CMAKE)\CMakeLists.txt:2 (project):
1> [CMake] The CMAKE_CXX_COMPILER:
1> [CMake]
1> [CMake] icx-cl
1> [CMake]
1> [CMake] is not a full path and was not found in the PATH. Perhaps the extension is
1> [CMake] missing?
1> [CMake]
1> [CMake] Tell CMake where to find the compiler by setting either the environment
1> [CMake] variable "CXX" or the CMake cache entry CMAKE_CXX_COMPILER to the full path
1> [CMake] to the compiler, or to the compiler name if it is in the PATH.

Tried to compile my project for WSL2 with these changes in CMakePresets.json:

    {
      "name": "linux-debug",
      "displayName": "Linux Debug",
      "generator": "Ninja",
      "binaryDir": "${sourceDir}/out/build/${presetName}",
      "installDir": "${sourceDir}/out/install/${presetName}",
      "cacheVariables": {
        "CMAKE_BUILD_TYPE": "Debug",
        "CMAKE_C_COMPILER": "/opt/intel/oneapi/compiler/latest/bin/icx",
        "CMAKE_CXX_COMPILER": "/opt/intel/oneapi/compiler/latest/bin/icx"
      },
      "condition": {
        "type": "equals",
        "lhs": "${hostSystemName}",
        "rhs": "Linux"
      },
      "vendor": {
        "microsoft.com/VisualStudioRemoteSettings/CMake/1.0": {
          "sourceDir": "$env{HOME}/.vs/$ms{projectDirName}",
          "intelliSenseMode": "windows-clang-x64"
        }
      }
    },

works without any issues!

Looks like setvars is not called on the VS start.

Any idea what I'm doing wrong?

Thanks
