This issue can be solved by copying the following DLLs to the exe path of the workbench:
libeay32.dll
ssleay32.dll
Make sure the DLLs match the QT version used in your MITK installer. For QT 5.11, we currently use OpenSSL 1.0.2g
The OpenSSL version can be found on the QT website.

For Qt 5.12.5 it is OpenSSl 1.1.1

It is not acceptable that there is a hidden manual process involved. There's legacy code in the XNAT plugin's CMakeLists.txt that tries to do that automatically but fails as it copies/installs the wrong files. To make the whole thing more visible, I will add the following two CMake cache variables to set the two DLLs. Manual copying and installing shouldn't be neccessary anymore then.
- MITK_OPENSSL_SSL_DLL
- MITK_OPENSSL_CRYPTO_DLL
BTW, OpenSSL is included in the Qt installer/maintenance tool. You find it under "Tools".
