compiling viewer.less fails

[churti]

Hello everyone,
until now i use angular-pdfjs-viewer 0.7.4 and everything works fine.
Now i was upgrading it (tryed it with both 0.8.0 and 0.8.1) and my build fails.
At the start of my build process i recompile the viewer.less with the global variable as it stands in the advanced configuration in the readme:
"lessc --global-var=\"pdfjsImagePath='../pdfjs'\" bower_components\\pdf.js-viewer\\viewer.less bower_components\\pdf.js-viewer\\viewer.css

As i said with 0.7.4 everything was ok. Now i get this:

SyntaxError: expected ')' got '/' in on line 2, column 4312:

And this fails:
border-image:url(@pdfjsImagePath/shadow.png)

This fails for all references to @pdfjsImagePath they all need to be enclosed in curly braces (78 occurance)

border-image:url(@pdfjsImagePath/shadow.png)

needs to become

border-image:url(@{pdfjsImagePath}/shadow.png)
