Why, then, don't you simply list the libraries in the correct order in
the target_link_libraries command? The add_dependencies command only
has an effect on targets, not external libraries. If indeed, they are
targets (which doesn't become clear from your code) you should do:
target_link_libraries( dlib_httpclient dlib )
target_link_libraries( ${PROJECT_NAME} dlib_httpclient )
Although, the libraries are static, CMake the remembers that
dlib_httpclient depends on dlib and in the last link-command you only
have to specify the dlib_httpclient library and CMake will do the rest
for you.

Yes, it has to do something with it...
Because at least when linking under Linux, if I added dlib BEFORE
dlib_httpclient (as is now the case), dlib_httpclient will complain
about
undefined symbols.
That's where the add_dependencies would come into play in my honest
opinion.
CMake should calculate the order in which to place the libraries to
link
with to honour all the calls made in the project. So in my case,
place dlib
behind dlib_httpclient.
What you are refering to is not a dependency in linkage, but a
dependency in
compilation. This is fine of course, but is not enough when compiling
libraries.

I think you misunderstand add_dependencies. The command adds a
dependency
of dlib_httpclient on dlib, i.e. dlib_httplclient DEPENDS ON dlib.
It has
nothing to do with the order the libraries appear on the command
line when
you link ${PROJECT_NAME}.

I have:
add_dependencies(dlib_httpclient dlib)
But in my cmakelists I have:
TARGET_LINK_LIBRARIES(${PROJECT_NAME} dlib dlib_httpclient)
Conclusion: it will change itself to "bin/libdlib.a
bin/libdlib_httpclient.a"
instead I would expect "bin/libdlib_httpclient.a bin/libdlib.a" as
I told
it
to add the dependency.
