compile twice to see custom message

edit

Hello all !

I have a package with a server that use a custom message for a service. The thing is that I need to compile twice for it to see the message for the server.

Lets say I suppress my build and devel in my catkin. Then I use catkin_make The first time I have this error :

fatal error: open_tld_3d/model.h: No such file or directory

Then catkin_make again and everything is fine this time.

I was wondering what could cause this behavior since everything seem to be ok the second time. I guess it's just that it is not able to see the message created at first and then on the second run it is able to finally find it but I don't know what to change to make it find the message on the firs run.

I don't want to put all my CMakeList.txt here (because they're big) so if you could please tell me what could be relevant to find the reason and I'll put it on this post.

Thanks a lot
