New real-time synchronization block (Closes #290)

[bernhard-thiele]

Added an enhanced real-time synchronization block (Blocks.OperatingSystem.RealtimeSynchronize) and deprecated the existing block (Blocks.OperatingSystem.SynchronizeRealtime).

I can no longer build (and run) the new test models test_MDDRealtimeSynchronize and test_MDDRTSync when running CTest (locally on Win). Is it by intention that these new test are differently configured than the other tests?

I can no longer build (and run) the new test models test_MDDRealtimeSynchronize and test_MDDRTSync when running CTest (locally on Win). Is it by intention that these new test are differently configured than the other tests?

Both tests use gtest but they still should work locally with CTest. I just checked that it works on my Linux machine at home. Haven't tested it with CTest on Windows. I only used the gtest Visual Studio plugin for running the tests there. Building on Windows (with Visual Studio) worked for me. Not sure if I have some stuff on my Windows machine which I didn't check in, but I don't think so.

Tested CTest under my Windows machine and it worked. I'm not sure what is going wrong for you. Maybe you can check again if it is still failing and post the error message.

CMake 3.13.3 reports during configuration:

CMake Warning (dev) at CMakeLists.txt:1 (project):
  Policy CMP0048 is not set: project() command manages VERSION variables.
  Run "cmake --help-policy CMP0048" for policy details.  Use the cmake_policy
  command to set the policy and suppress this warning.

  The following variable(s) would be set to empty:

    CMAKE_PROJECT_VERSION
    CMAKE_PROJECT_VERSION_MAJOR
    CMAKE_PROJECT_VERSION_MINOR
    CMAKE_PROJECT_VERSION_PATCH
This warning is for project developers.  Use -Wno-dev to suppress it.

I cannot build test_MDDRTSync due to failing build of gmock.

I generated the project with the GUI version of Cmake 3.12.0 and 3.13.1 under Windows 7 for Visual Studio 2017. Both versions didn't throw the configuration warnings which you got. This is my configuration:

If I build target test_MDDRTSync, it works without the gmock error, but it seems to use another build sequence:

This leaves me a bit puzzled.

Never mind the CMake config warning, which is gone if I reconfigure in an empty directory.

The gmock issue was reported in https://github.com/google/googletest/issues/1848. My remedy is to not treat warnings as errors, i.e., change /WX to /WX- in VS 2010.

[beutlich]

Ah, the CMake config warning occurs, if you configure a second time.

[bernhard-thiele]

Ah, the issue is related to VS 2010 which I didn't test. Thanks for coming up with this nice fix, I integrated the logic into the CMake config.

[bernhard-thiele]

@beutlich Thanks for testing! Hopefully, everything works now as it should. I will merge the PR.
