Configuring CMake and Microsoft Visual Studio 2019 for Use with Intel Compilers

Question

I tried to determine if CMake is an option to simplify the cross-platform development of a c++ library that I am working on. Linux is done. Now, I am trying to use CMake on windows. Setting up CMake using the Visual Studio Generators of CMake was also not an issue. I tested it also on a simple program "hello_world.cpp".

mkdir build
cd build
cmake ..
msbuild hello_world.sln

The problem arises when I try to configure CMake for Microsoft Visual Studio with Intel Compilers as explained by Intel . Following Intel for the simple program "hello_world.cpp", I did the following in the power-shell

mkdir build
cd build
cmd.exe "/K" '"C:\Program Files (x86)\Intel\oneAPI\setvars.bat" && powershell'
cmake -T "Intel(R) oneAPI DPC++ Compiler" -DCMAKE_CXX_COMPILER="dpcpp" ..

the output was

The problem seems to be VCTargetsPath. Microsoft calls it a macro referencing %VSINSTALLDIR%MSBuild\Microsoft\VC<version>\. At this point, google did not help much in answering my question on checking if VCTargetPah is set correctly. Where is it defined? Registry, System variable, or in some project files of VisualStudio? I did not quite understand this and I do not know much about windows programming.

Is it a bug? Is VCTagetsPath the problem at all? Can I do something about it? Any help on how to proceed would be appreciated.

hello_world.cpp:

#include<iostream>
int main(){std::cout << "Hello World\n"; return 0;}

Answer 1

Can you try this:

cmake -DCMAKE_CXX_COMPILER=icx ..

instead of this:

cmake -T "Intel(R) oneAPI DPC++ Compiler" -DCMAKE_CXX_COMPILER="dpcpp" ..

FYI I think you were looking at old documentation, this was the latest for 2022.1 I think.
