storeItemInCache SOULPatchHost

hello everybody, I am sure this is my lack of knowledge in cached object code chunks but I can’t figure out which kind of sourceData I have to pass to:

soul::patch::CompilerCacheFolder.storeItemInCache (const char* key, const void* sourceData, uint64_t size)

I am developing a SOULPatch host with Juce that autoload a .soulpatch file when it starts, I am guessing I need a compilerCache for my SOULPatchAudioPluginFormat constructor to speed up the process. right?

thanks for the help.
