[CMake] AUTOMOC with files on different folders

[Tiago Macarios]

Hi Attila,

Thank you for your help. You are right, if I apply the following
modifications it works indeed:

set( proj_HEADER
    include/a.h
)

add_library(proj SHARED ${proj_SOURCE} ${proj_HEADER})

But now I got a second question. Why is adding the header files necessary?
(Sorry the possibly naive question)

I thought that adding the header files to the target was an anti-pattern (
http://voices.canonical.com/jussi.pakkanen/2013/03/26/a-list-of-common-cmake-antipatterns/
). Is it related to moc generating header files during the build? If so why
is it not a problem when everything is on the same folder?

Tiago
