Issue with the Ninja generator in CMakePresets.json with Visual Studio 2022 and v140 toolset

Question

Hello,

When using the Ninja generator in CMakePresets.json under Visual Studio 2022 (17.6.2 and priors) , with toolset = "v140,host=x64" (external) and architecture = "x86" (external), cmake is unable to find the compiler, and some dlls are not found (like mspdbcore.dll). However it works with the x64 architecture.

I installed the Visual 2015 compiler through the menu Get Tools and Features from Visual 2022 (looking for v140).

I open the solution by right clicking on the code repo in windows explorer, then click "open with visual studio".

I'm a bit afraid to have to call vcvars before, but it's not really what I'd expect from visual studio, as it's not forbidden to define configurations for multiple compilers in the same CMakePresets.json (and that's the need of my team).

As the external strategy is advised when using Ninja, I believe that the issue is somewhere in the Visual Studio IDE that might be failing to call the expected vcvars script from Visual 2015.

A fix for that would.be welcome :)

Thank you !

Hi @Tanguy , 

Welcome to Microsoft Q&A! 

Please refer to the document to configure your CMake Presets. 

If it doesn’t work, you can report it in dedicated CMake forum. Thanks for your understanding!

Sincerely,

Anna
