Root Cause

Cygwin environment cannot convert Windows-style paths to Cygwin paths due to missing cygpath utility or misconfigured environment.

Workarounds

  1. 85% success Ensure cygpath is in PATH: run `which cygpath` in Cygwin terminal. If missing, reinstall Cygwin with 'cygwin' package. 
    Ensure cygpath is in PATH: run `which cygpath` in Cygwin terminal. If missing, reinstall Cygwin with 'cygwin' package.
  2. 90% success Use native Windows CMake (not Cygwin version) by invoking `cmake.exe` from cmd or PowerShell.

中文步骤

  1. 确保 cygpath 在 PATH 中：在 Cygwin 终端中运行 `which cygpath`。如果缺失，重新安装 Cygwin 并包含 'cygwin' 包。
  2. 使用原生 Windows CMake（而不是 Cygwin 版本），通过 cmd 或 PowerShell 调用 `cmake.exe`。

Dead Ends

Common approaches that don't work:

  1. Manually set the path in CMakeLists.txt using absolute Windows path. 60% fail

    Cygwin's CMake still expects Cygwin paths internally, causing further errors.

  2. Reinstall Cygwin with default packages only. 40% fail

    Cygwin's cygpath is part of the base install; missing it indicates a corrupted environment.
