cannot find valid Visual Code Studio install

[Erik Joelsson]

There seems to be something with the absolute path elimination that 
doesn't work when the workspace is located inside the c:/cygwin64 dir. 
As a workaround, you can either try moving the source to a directory 
outside of c:/cygwin64 or run configure with 
--enable-absolute-paths-in-output.

I'm still investigating the exact cause.
