There is no reason for this. CMake knows that it does not have to compile
header files, so it wont add compile rules for them e.g. in Makefiles. Just
always add them to the project, this has some additional benefits for
generated headers and the like.

You just need to make sure that it goes into the lib folder first, before
going into src. So the top level CMakeLists.txt should have
add_subdirectory(lib)
# or lib/reverse above, depending if you have something in lib/
add_subdirectory(src)
