Suggestion: change bool enableX, bool enableY into bit-wise OR'ed parameter, to make the API more readable.

May I ask where to start, i.e. which files I should modify or which directories I should put my own files in?

Look at nfd-local-control-header.hpp and how it's used in Interest and Data types.

I'm also thinking about making LocalControlHeader a Tag (see tag.hpp and tag-host.hpp), because it makes sense only in limited context.

Is NoCache a boolean type? I suppose that I should use prependBooleanBlock() to add a NoCache block to a CachingPolicy block.

I don't know about this area of code.
See spec for how the encoded packet looks like.

The spec says that the NoCache TLV has no value. I am not sure how to prepend a no value block to the CachingPolicy TLV.

I'm unfamiliar with this area. I've asked ndn-lib. Please wait for an answer from the mailing list.

I can't find the test case for the nfd-local-control-header.hpp. Should I create one for it?

Yes, you must.

Actually, I found it is tested at the test case of interest, i.e. test-interest.cpp.

I encountered this linker error. Do you have any idea what causes it? I have implemented a CachingPolicy class and put it into the file nfd-local-control-header.hpp together with the LocalControlHeader class.

You should share the code first (e.g., gerrit). Without seeing the code causing problem, I don't think anybody here would be able to give a good advise.
