Kit with preferredGenerator isn't finding generator

[gcampbell-msft]

          Reproduce issue like this:

Install jom (https://wiki.qt.io/Jom).
Add jom.exe location to your system PATH.
In cmake-tools-kits.json add the following kit:
{"name": "JOM test kit", "preferredGenerator": {"name": "NMake Makefiles JOM"}}

Open a CMake project and try to configure it with the "JOM test kit".
You will get the error:

[main] Unable to determine what CMake generator to use. Please install or configure a preferred generator, or update settings.json, your Kit configuration or PATH variable. Error: No usable generator found.

My scenario is the following:

I have a CMakePresets.json in which I have this:

  "configurePresets": [
    {
      "name": "windows",
      "inherits": "base",
      "cacheVariables": {
        "CMAKE_C_COMPILER": "cl.exe",
        "CMAKE_CXX_COMPILER": "cl.exe"
      }
    }
  ]

And base contains the following, that is relevant:

    "generator": "Ninja",
    "toolchainFile": "$env{VCPKG_ROOT}/scripts/buildsystems/vcpkg.cmake"

I don't have the compiler in my PATH, and I was relying on the invocation of the devenv from the extension.

In the v1.18 it is working fine, starting from v1.19 it isn't resolving... The PR #4024 fixed the environment variables expansion in the CMakePresets.json, but not this specific case that was described above.

Ah, it might be that the PR from #4028 fixes this? I'll try to reproduce your project, despite not having a full repro. Thanks

@marcogmaia Could you test with the vsix from this comment: #4023 (comment)?

After some investigation, I think I see what's happening. Could you try this vsix here?

Still not working.

Could you please make a minimal repro so that I can directly test so that I can best investigate?

I've confirmed with a test I made with your preset that the toolchain file is being correctly grabbed, and that the environment includes the developer environment. Therefore, I'll need more information and more concrete repro in order to see what's going on. Thanks.

[gcampbell-msft]

@marcogmaia I've tested that this configure preset works as expected:

{
"version": 8,
"configurePresets": [
{
"name": "base",
"toolchainFile": "$env{VCPKG_ROOT}/scripts/buildsystems/vcpkg.cmake",
"generator": "Ninja"
},
{
"name": "windows",
"inherits": "base",
"cacheVariables": {
"CMAKE_C_COMPILER": "cl.exe",
"CMAKE_CXX_COMPILER": "cl.exe"
}
}
]
}
