```
$ninja abseil_dll

cmake command are like
```

### Steps to reproduce the problem

1. generate zip tarball with depot_tools' [package_from_installed.py script](https://chromium.googlesource.com/chromium/tools/depot_tools.git/+/refs/heads/main/win_toolchain/package_from_installed.py), make sure you have visual studio 2026 installed.
2. cd $HOME && git clone https://github.com/hukeyue/vstoolchain
3. extract the zip from step1 into $HOME/vstoolchain
4. cd $HOME && git clone https://github.com/abseil/abseil-cpp
5. cd $HOME/vstoolchain && WITH_CPU=x86 ./build-abseil.sh
6. cd $HOME/abseil-cpp/build-msvc-x86-dynamic && ninja abseil_dll
