在尝试使用 vcpkg 安装 GTK 时，它无法提取libexpat-libexpat-R_2_2_6.tar.gz：
Building package expat[core]:x64-windows...

-- Extracting source C:/Users/USER/git/vcpkg/downloads/libexpat-libexpat-R_2_2_6.tar.gz
CMake Error at scripts/cmake/vcpkg_execute_required_process.cmake:56 (message):

Working Directory: C:/Users/USER/git/vcpkg/buildtrees/expat/src/TEMP
Error code: 1
See logs for more information:
C:\Users\USER\git\vcpkg\buildtrees\expat\extract-err.log
提取-err.log：
CMake Error: Problem with archive_write_header(): Can't create ''
CMake Error: Current file: libexpat-R_2_2_6/README.md
CMake Error: Problem extracting tar: C:/Users/USER/git/vcpkg/downloads/libexpat-libexpat-R_2_2_6.tar.gz
手动运行 tar 会导致：
> tar xjf C:/Users/USER/git/vcpkg/downloads/libexpat-libexpat-R_2_2_6.tar.gz
libexpat-R_2_2_6/README.md: Can't create '\\\\?\\C:\\Users\\USER\\git\\vcpkg\\buildtrees\\expat\\src\\TEMP\\libexpat-R_2_2_6\\README.md'
tar: Error exit delayed from previous errors.

编辑：
tar 错误是预料之中的，问题体现在 cmake 中，其中预期输出（请参阅 extract-err.log）应该是：
cmake -E tar: warning: skipping symbolic link "libexpat-R_2_2_6/README.md" -> "expat/README.md".

看起来这是一个活跃的 cmake 问题https://gitlab.kitware.com/cmake/cmake/issues/19102
