example /usr/src/bitcoin, AND not under /mnt/d/. If this is not the case the dependency autoconf scripts will fail.
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.

Build using:
PATH=$(echo "$PATH" | sed -e 's/:\/mnt.*//g') # strip out problematic Windows %PATH% imported var
+ sudo bash -c "echo 0 > /proc/sys/fs/binfmt_misc/status" # Disable WSL support for Win32 applications.
