描述

I'm using CMake and CTest to build and run my tests.

On Linux I can produce color googletest output with CTest, like this: GTEST_COLOR=1 ctest -V

On Windows I tried something similar in powershell: $Env:GTEST_COLOR=1; ctest -V

However the output is still not colored. How can I achieve the desired colored output?

I'm using Googletest 1.10.0 and CMake 3.17.3

研究方向
Investigate how GoogleTest handles color output on Windows, especially with PowerShell and CTest. Check the source code in googletest/src/gtest.cc for color detection logic. Test if the GTEST COLOR environment variable works with different shells (cmd vs PowerShell) and if the gtest color=yes flag bypasses the issue. Also examine CTest's output handling to see if it strips ANSI codes. Provide a concrete reproduction and potential workaround.
