 When you have all static libraries (Qt5, libisds and dependencies) run the following commands. These must be run from a working desktop session on OS X as the scripts accesses some resources that aren't available on a plain terminal session (e.g. when logged-in via ssh).
 ``` shell
-./scripts/build_osx_dmgs.sh -d -s ${SDK_VER}
+QT_VER="5.7.1" ./scripts/build_osx_dmgs.sh -d -s ${SDK_VER}
 ```
 Occasionally it happens that the target .dmg file fails to build properly (because of some asynchronous actions). In such cases just re-run:
 ``` shell
-./scripts/build_osx_dmgs.sh -D -s ${SDK_VER}
+QT_VER="5.7.1" ./scripts/build_osx_dmgs.sh -D -s ${SDK_VER}
 ```
 This will skip the compilation and will only build the package.
