Issue building HISE plugin

[toxonic]

I've been trying to build the plugin version of HISE and got the following error message:

In file included from ../../../../JUCE/modules/juce_audio_plugin_client/juce_audio_plugin_client_VST2.cpp:26,
                 from ../../JuceLibraryCode/include_juce_audio_plugin_client_VST2.cpp:9:
../../../../JUCE/modules/juce_audio_plugin_client/VST/juce_VST_Wrapper.cpp:87:10: fatal error: pluginterfaces/vst2.x/aeffect.h: No such file or directory
   87 | #include "pluginterfaces/vst2.x/aeffect.h"

I think, I do remember, I already had that issue yet, but I don't know anymore, how I solved it... :-/
The path to the VST (Legacy) SDK Folder looks fine, and it contains the aeffect.h header file, but it seems that I must be missing something.
Anyone can help?

@toxonic Have you extracted the SDK zip file in the tools folder?

@d-healey Hey David, yeah I did. But I already managed it to compile the plugin, just by changing the path in the juce_VST_Wrapper.cpp to an absolute path on my system.
Not an elegant solution, but worked for me. But nevertheless, I'd love to know, why it won't compile otherwise.
I tried to point to the VST3 SDK folder as well as the vst2.x folder inside it, none of them worked.
I also renamed the VST3 SDK folder, to VST3_SDK , because I thought, it might got something to do with the empty space in the directory name... didn't work either.
