No thundersvm.dll appears on Windows [Question] #133

Hi, first thanks to your excellent work on enhancing SVM.

I have read the build docs and follow your advice to build on Windows 8. It seems everything works well but I could not find the thundersvm.dll file. I don't know what's wrong.

My environment is:

And when I run the code below for compling,

$cmake .. -DCMAKE_WINDOWS_EXPORT_ALL_SYMBOLS=TRUE -DBUILD_SHARED_LIBS=TRUE -G "Visual Studio 15 2017 Win64" -Tv140

Such logs was printed and no errors was thrown.

I have tried compiling without GPU and run codes below, but the same situation appeared.

$cmake .. -DCMAKE_WINDOWS_EXPORT_ALL_SYMBOLS=TRUE -DBUILD_SHARED_LIBS=TRUE -DUSE_CUDA=OFF -DUSE_EIGEN=ON -G "Visual Studio 15 2017 Win64" -Tv140

Any advice please...? Thanks !

Please build the library first. After you use the cmake command, you can find "thundersvm.sln" file. You can open this file using Visual Studio and build the library inside it. Then you can see "thundersvm.dll" file. Thanks.
