This means you cannot use a directory that is located directly on the host Windows file system to perform the build. This means you cannot use a directory that is located directly on the host Windows file system to perform the build.
Additional WSL Note: WSL support for [launching Win32 applications](https://docs.microsoft.com/en-us/archive/blogs/wsl/windows-and-ubuntu-interoperability#launching-win32-applications-from-within-wsl)
results in `Autoconf` configure scripts being able to execute Windows Portable Executable files. This can cause
unexpected behaviour during the build, such as Win32 error dialogs for missing libraries. The recommended approach
is to temporarily disable WSL support for Win32 applications.
