how to compile libvpx for windows?

[alexander...@gmail.com]

Hi guys, I'm having troubles compiling libvpx for window using VS2012 on windows 7.

I follow the instructions written here : http://www.webmproject.org/code/build-prerequisites/, using cygwin.

I added the folder containing msbuild.exe to PATH  (C:\windows\blahblahblah..), I ran ./configure --target=x86-win32-vs11 --enable-static-msvcrt, and make.

make terminates saying:

Why make feeds Cl.exe with cygwin-style path ?! Please help, I wasted half of a day trying various approaches to compile this f. libvpx...

mingw-based visual studio builds are tested nightly, so for now prefer that.

I've had trouble with cygwin in the past setting the mount prefix or
doing cross-drive configures.
If you file a bug [1] make sure to note your checkout and build paths
as well as the configure command line.
