Windows: environmentSetupScript in kits doesn't seem to properly work with .bat

Brief Issue Summary

On Windows, I'm trying to configure CMake tools in order to call a file activate_run.bat generated by conan in my build folder. This file is required because:

• I build qt from source with all libraries shared, so rcc.exe (executed at configure time in CMake if using AUTORCC ON) is linked to shared zlib and zstd.
• activate_run.bat adds to PATH all the bin folders where dll's dependencies are stored, so that rcc.exe can find dll.

I've added this line in kits:

    "environmentSetupScript": "${workspaceRoot}/build/${buildKit}_${buildType}/activate_run.bat"

(${workspaceRoot}/build/${buildKit}_${buildType} is the custom value of my cmake.buildDirectory, but I've also tried with an hardcoded absolute path like "environmentSetupScript": "D:/projects/test/build/msvc2019_x64_x64_Release/activate_run.bat").

But it doesn't work, rcc.exe fails at execution time during CMake configuration, meaning that dll files are not in PATH.

If I run the following commands in x64 Native Tools Command Prompt for VS 2019, everything works like a charm:

activate.bat
cmake <path_to_project> -DCMAKE_BUILD_TYPE:STRING=Release -G Ninja
cmake --build .

Here is the content of activate_run.bat:

@echo off
SET "CONAN_OLD_PATH=%PATH%"

FOR /F "usebackq tokens=1,* delims==" %%i IN ("D:\projects\test\build\msvc2019_x64_x64_Release\environment_run.bat.env") DO (
    CALL SET "%%i=%%j"
)

SET "CONAN_OLD_PROMPT=%PROMPT%"
SET "PROMPT=(conanrunenv) %PROMPT%"

Content of environment_run.bat.env read by activate_run.bat to fill PATH:

Expected:

1. run conan install outside of CMake tools with virtualrunenv generator.
2. add absolute path to activate_run.bat (generated by step 1) in environmentSetupScript of kits
3. configure CMake successfully

Apparent Behavior:

1. run conan install outside of CMake tools with virtualrunenv generator
2. add absolute path to activate_run.bat (generated by step 1) in environmentSetupScript of kits
3. configure CMake fails

Other Notes/Information

Reproduce the Windows case using conan's virtualrunenv generator, the kit's environmentSetupScript, and the provided activate_run.bat, then inspect how CMake Tools launches the configuration command. Done means configuring the project succeeds and rcc.exe can find its DLL dependencies through the batch-script environment.
