Description

General summary/comments

Interpret Linux paths, like:

/opt/OpenBLAS/bin

as

C:\Users\MyUser\AppData\Local\Programs\stack\x86_64-windows\msys2-20150512\opt\OpenBLAS\bin

Steps to reproduce

  1. Try to build hmatrix library under Windows

Expected

Linux paths in .yaml files under Windows to be reinterperted.

Research direction
The issue requests interpreting Linux style paths (e.g., /opt/OpenBLAS/bin) as MinGW paths on Windows. To implement this, examine how Stack currently handles configuration paths in YAML files, particularly for package databases and extra include/lib directories. Look at the codebase for any existing path conversion utilities, especially around MSYS2 integration. The solution likely involves detecting Windows and converting absolute Unix paths to their corresponding locations under the MSYS2 root (e.g., C:\msys64\opt...). Check the discussion in the issue for any additional context, and consider using the `cygpath` utility or similar.
