Older versions of cmake don't support the -E env option which was added in r250335, causing the build to fail with:

    [...]

    CMake Error: cmake version 3.0.2

    Available commands:

    [...]

This patch fixes this by invoking codesigning as it was before the commit if the cmake version is less than than 3.2.
