Cannot find idl file if it's in non-related folder

[xakod]

I have a bit strange project struct... :)
For example, I have:

/root

/mylib

/source

/mylib.idl

/project

CMakeLists.txt with add_idl

So I use add_idl(mylibIDL ${CMAKE_SOURCE_DIR}/mylib/source/mylib.idl).
Now, look at
${CMAKE_SOURCE_DIR}/mylib/source/mylib.idl
function(add_idl _target _idlfile) and then at
https://github.com/apriorit/FindIDL/blob/master/cmake/FindIDL.cmake#L19
COMMAND midl.exe ARGS /${MIDL_ARCH} /env ${MIDL_ARCH} /nologo ${CMAKE_CURRENT_LIST_DIR}/${_idlfile}

If we expand ${_idlfile} here it will become
COMMAND midl.exe ARGS /${MIDL_ARCH} /env ${MIDL_ARCH} /nologo ${CMAKE_CURRENT_LIST_DIR}/${CMAKE_SOURCE_DIR}/mylib/source/mylib.idl
Now we have a problem :)
