Error loading kext in Mojave

[romeroadrian]

I'm running 10.14.6, the build runs fine (xcode 11.3) but I get this error while loading the kext

(kernel) kxld[org.syscl.driver.CPUTune]: The super class vtable '__ZTV9IOService' for vtable '__ZTV7CPUTune' is out of date. Make sure your kext has been built against the correct headers.

This issue #2 mentions to install the Mojave SDK to fix the error but didn't solve it for me, not sure if I'm missing something besides installing the SDK package that comes in the xcode command line tools.
