Bug#758259: spring: FTBFS with cmake 3.0

Source: spring
Version: 96.0+dfsg-2
Severity: normal

Hi,

I have prepared cmake 3.0 in experimental and would like to upload it to
unstable soon.

spring fails to build from source with cmake 3.0 because
tools/unitsync/test/CMakeLists.txt claims it needs compatibility with cmake 2.2.

>CMake Error in tools/unitsync/test/CMakeLists.txt:
>  You have set CMAKE_BACKWARDS_COMPATIBILITY to a CMake version less than
>  2.4.  This version of CMake only supports backwards compatibility with
>  CMake 2.4 or later.  For compatibility with older versions please use any
>  CMake 2.8.x release or lower.

This is already fixed upstream:

Cheers,
