CMake Error (dev): uninitialized variable 'cxx_strict_flags'.

shrek1402 commented 1 year ago

Describe the bug

I get an error message when building a project

Does the bug persist in the most recent commit? Yes

I use preset:

"configurePresets": [
    {
      "name": "cmake-pedantic",
      "hidden": true,
      "warnings": {
        "dev": true,
        "deprecated": true,
        "uninitialized": true,
        "unusedCli": true,
        "systemVars": false
      },
      "errors": {
        "dev": true,
        "deprecated": true
      }
    },

$ cmake --preset=dev

If I understand correctly, then the problem is here. And the solution is very simple - you either need to always define the variable 'cxx_strict_flags', or add a condition to define 'cxx_strict'

Hi, Any news about the fix?
