Bug#757282: freecad: spurious build-dependency on libswscale-dev

[Andreas Cadhalpun]

Source: freecad
Version: 0.14.3702+dfsg-1
Severity: whishlist

Dear Maintainer,

currently freecad build-depends on libswscale-dev, but it seems not to 
use this library, as none of the created binary packages depend on 
libswscale.

Therefore, please remove this spurious build-dependency.

Best regards,
Andreas
