Using Intel C++ compiler with Visual Studio 2017/2019 cmake

[Sergei]

Currently we use Visual Studio 2017 targeting Windows with Visual Studio solutions/projects files.
We want to build/debug our product for both Windows/Linux and trying to use Visual Studio build with cmake.
According to docs.microsoft.com/en-us/cpp/build/cmakesettings-reference?view=vs-2019 :
---

Any custom environment can be used, or these predefined environments:
linux_arm: Target ARM Linux remotely.
linux_x64: Target x64 Linux remotely.
linux_x86: Target x86 Linux remotely.
msvc_arm: Target ARM Windows with the MSVC compiler.
msvc_arm_x64: Target ARM Windows with the 64-bit MSVC compiler.
msvc_arm64: Target ARM64 Windows with the MSVC compiler.
msvc_arm64_x64: Target ARM64 Windows with the 64-bit MSVC compiler.
msvc_x64: Target x64 Windows with the MSVC compiler.
msvc_x64_x64: Target x64 Windows with the 64-bit MSVC compiler.
msvc_x86: Target x86 Windows with the MSVC compiler.
msvc_x86_x64: Target x86 Windows with the 64-bit MSVC compiler.

(though config dialog also mentions Mingw64 as an option).

Can you give recommendations how to configure VS 2017/2019 cmake to use Intel C++ compiler on both Windows and Linux?

Regards,

Sergei.

After you "source /intalled_dir compilervars.csh", then see where gcc/g++ are called in your Makefile thenchange to icc/icpc

[Sergei]

Viet,

Thank you for your response.

CMake generates Makefile files (Unix Makefile generator is configured for CMake only for Linux build files output). For Windows, VS2017/2019 with CMake generates Ninja build files.

Therefore, your advice is not applicable.

Regards,

Sergei.

How to use Intel C++ compiler with VS2017/VS219 CMake "open folder" workflow, I give example for VS2019 and Intel C++ compiler update 4:

1. Create vs2019.cmd with the following text:

---

call "C:\Program Files (x86)\IntelSWTools\compilers_and_libraries_2019.4.245\windows\bin\ipsxe-comp-vars.bat" intel64 vs2019
start "VS2019" /B "C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\Common7\IDE\devenv.exe"

---

2. . Click on vs2019.cmd.

3. In VS2019 edit your CMakeSettings.json config file, add the following (for Release configuration):

---

    {
      "name": "x64-IntelEnv-Release",
      "description": "Start visual studio from Intel C++ compiler environment cmd window",
      "generator": "Ninja",
      "configurationType": "Release",
      "buildRoot": "${workspaceRoot}\\..\\cmake-build\\${name}",
      "installRoot": "${workspaceRoot}\\..\\cmake-install\\${name}",
      "cmakeCommandArgs": "",
      "buildCommandArgs": "-v",
      "ctestCommandArgs": "",
      "inheritEnvironments": [ "msvc_x64_x64" ],
      "variables": [
        {
          "name": "CMAKE_CXX_COMPILER",
          "value": "icl.exe",
          "type": "FILEPATH"
        },
        {
          "name": "CMAKE_C_COMPILER",
          "value": "icl.exe",
          "type": "FILEPATH"
        }
      ]
    }

---
4. Select "x64-IntelEnv-Release" in "Configurations" dropbox. Build.
