IntelliSense & Code Completion Fails Unless Compiler Paths are Added to PATH Environmental Variable

Bug Summary and Steps to Reproduce

The ms-vscode.cpptools extension fails to evaluate the PATH variables provided by e.g. a CMake preset, terminal.integrated.env.windows or cmake.environment (or any other cmake.*Environment) variables, nor is there an option to explicitly specify a PATH environmental variable to be used by the extension, like C_Cpp.path.

This results in the build environment not being detected correctly. IntelliSense and code completion does not work.

Building via the ms-vscode.cmake-tools extension works perfectly fine, since it is evaluating the environment specified in a CMakePresets.json (s. excerpt):

{
    "configurePresets": [
        {
            "name": "<PRESET_NAME>",
            "displayName": "'<PRESET_NAME>' config",
            "description": "'<PRESET_NAME>' configure using 'Unix Makefiles' generator",
            "generator": "Unix Makefiles",
			"environment": {
                "PATH": "<PATH_TO_COMPILER_ROOT>/sysroots/x86_64-petalinux-mingw32/usr/bin:$penv{PATH}"
            }
        }
    ],
  
}

I do not want to alter the PATH environmental variable of the system, in order not to create conflicts with other projects I am working on. This means I have to manually specify the path every time in a CMD.exe,

C:\PATH\TO\PROJECT>set PATH=<PATH_TO_COMPILER_ROOT>\sysroots\x86_64-petalinux-mingw32\usr\bin;%PATH%

C:\PATH\TO\PROJECT>code .

or create a batch file, to start code with the correct environment.

Am I missing a way how to set the environment, particularly for a project - not system wide?

Could you please add a feature to set the PATH used by ms-vscode.cpptools ? Ideally the one from the CMake preset is automatically used.

Configuration and Logs

[7/10/2026, 12:12:00 PM] Unable to resolve configuration with compilerPath "<PATH_TO_COMPILER_ROOT>/sysroots/x86_64-petalinux-mingw32/usr/bin/aarch64-xilinx-linux/aarch64-xilinx-linux-g++.exe".  Using "cl.exe" instead.
