Azat Khuzhin 35335f07db Fix INTERFACE_COMPILE_DEFINITIONS for IMPORTED targets
INTERFACE_COMPILE_DEFINITIONS does not work IMPORTED targets:

From 3.6:

    Specify compile definitions to use when compiling a given <target>.
    The named <target> must have been created by a command such as
    add_executable() or add_library() and must not be an Imported Target.

Since 3.11:

    Specify compile definitions to use when compiling a given <target>.
    The named <target> must have been created by a command such as
    add_executable() or add_library() and must not be an ALIAS target.

And this causes the -Wundef warning:
    src/Functions/FunctionsHashing.h:1326:5: warning: 'USE_XXHASH' is not defined, evaluates to 0 [-Wundef]
