netgen/cmake_modules/SuperBuild.cmake
Matthias Hochsteger cb8bef9423 Force rebuild of Netgen subproject when building the Superbuild 
CMake is using stamp files to check if the external projects are out
of date. There is an option 'BUILD_ALWAYS 1' of ExternalProject_Add,
but it is not available prior to CMake 3.1.

To work around it, this commit solves two problems at once:

- Add a new step 'check_submodules' between configure and build
  to check if all submodules are up to date. This step has the option
  'ALWAYS 1', which means it is always considered outdated.

- Since 'build' depends on the above step, it will always be started
