[dm-vodopyanov]

The error is:

/repo/sycl-fusion/jit-compiler/include/JITContext.h:61:8: error: ‘unique_ptr’ in namespace ‘std’ does not name a template type
   61 |   std::unique_ptr<llvm::LLVMContext> LLVMCtx;
      |        ^~~~~~~~~~
/repo/sycl-fusion/jit-compiler/include/JITContext.h:18:1: note: ‘std::unique_ptr’ is defined in header ‘<memory>’; did you forget to ‘#include <memory>’?
