New in version 3.16.
When this property is
ON, CMake will generate the
-p path prefix
AUTOMOC enabled Qt targets.
To generate the path prefix, CMake tests if the header compiled by
is in any of the target
include directories. If so, CMake will
compute the relative path accordingly. If the header is not in the
include directories, CMake will omit
-p path prefix option.
moc usually generates a
relative include path in that case.
AUTOMOC_PATH_PREFIX is initialized from the variable
CMAKE_AUTOMOC_PATH_PREFIX, which is
OFF by default.

For reproducible builds it is recommended to keep headers that are
compiled in one of the target
include directories and set
ON. This ensures that:
mocoutput files are identical on different build setups,
mocoutput files will compile correctly when the source and/or build directory is a symbolic link.
