 OleSsItemHandler may use libUEMF library to draw some of OLE preview based on WMF/EMF metafiles.
 
 Test existence of libUEMF library in folder ThirdParty/libUEMF.
 If files are missing :
 1. Download it from https://github.com/mathog/libUEMF into this folder.
 2. Copy Kernel/Extensions/OleSsItemHandler/ThirdParty/libUEMF/CMakeLists.txt into ThirdParty/libUEMF too.
 3. Remove useless *.h files with the redirection into include subfolder.
 4. Regenerate and rebuild projects.

 libUEMF uses libiconv library. But it is a system library for unix-based platforms only.
 Next steps are needed to get libiconv on Windows.
 Also published packages for MSVC on Windows have not an ability to regenerate projects.
 Therefore the next is usable only with git-level access to ODA sources.

 If files are missing :
