[vlc-devel] [PATCH 3.0 07/10] package/win32: build.sh: add an option to set the PDB source file mapping

[Steve Lhomme]

This can be useful when cross-compiling. The UNIX pathes need to be mapped
to a Windows path that the debugger can use.

So if you build with "-D c:/vlc" the debugger will look for VLC sources in
c:\vlc, as if they were originally built from there.

(cherry picked from commit 990d460b71500b7c9906778b7b4300ff5600c7aa)
