How to specify target os in kit with toolchainFile?

[RichardLuo0]

I have a kit like this;

  {
    "name": "WASM",
    "toolchainFile": "C:\\emsdk\\upstream\\emscripten\\cmake\\Modules\\Platform\\Emscripten.cmake"
  }

It seems the ${buildKitTargetOs} becomes unknown. so how do I specify the target os?

@RichardLuo0 It looks to me like we get the target os from the output of the compiler test that we run here:

vscode-cmake-tools/src/kits/kit.ts

Line 191 in 7798425

for (const line of lines) {

.

How do you define your compiler in this kit? Having not defined your compiler may be the issue here.

Outside of this, I'd encourage you to make use of CMakePresets rather than Kits, since this is what we primarily support and it is officially supported by Kitware (developer of CMake).

Thanks!

The compiler is defined inside toolchain file.

@RichardLuo0 Then there is a possibility that this is a bug, could you create an issue for this and we can investigate it further when we can ?
