```shell
`MSYS2_ARG_CONV_EXCL=$MY_INSTALL_DIR2 cmake -G"MinGW Makefiles"\
      -DgRPC_INSTALL=ON \
      -DgRPC_BUILD_TESTS=OFF \
      -DCMAKE_INSTALL_PREFIX=$MY_INSTALL_DIR2 \
      ../..`

```

cmake generate “MinGW Makefiles” that contains windows and unix path, how to force those paths to be only unix path or windows path?

**official cmake docs, official msys2 docs, google search, AI can not give me answers**

What is the issue with having mixed paths?
