OK, two days later, I answer my old question and raise new ones:
for the OMSimulator in Win10, I changed the git config "git config --global core.autocrlf true", instead of "input" given in the .txt file.
The main issue in Win10 is the C/C++ compiler; my solution is 1) install newest cmake.exe, 2) add the existing mingw64 in user environmental variable #path. 
The compilation is smooth; 3) put /OMSimulator/install/mingw/bin above all openmodelica-related item in user environmental variable #path.

But the OMSimulation documentation, many things are misleading. For example,  there is no such "example.lua". or it denotes only one example file with lua format.
I try the OMSimulation with testsuiter/AircraftVehicleDemonstrator/AircraftVehicleDemonstrator.lua . The results contain many warnings, I have no idea if everything is OK or not.
