Let me explain this with images;
When you download VST sdk from Steinberg, the folder comes like this....

As you see, there is a VST3_SDK folder. You need to remove "_" sign and give a space. So the new name will be like this:
0_1520401710373_Second.jpg
Copy this "VST3 SDK" folder to Hise-master > tools > SDK folder. So Hise-master > tools > SDK folder will be like this:
0_1520401857449_Hise-master.jpg
As you see, you also need to download ASIOSDK2.3 from Steinberg too. And it's name must be like in the photo. (you don't need to download AAX SDK if you don't want to make AAX plugins.)
I hope it's clear. :)
And believe in me, I don't understand what you are talking about sometimes in what you write :) You can use Google translate my friend :)
