Hi,
I finally managed to test and build syncevolution as debian package,
installed in fresh Stretch with TDE 14.1 (DEVELOPMENT) and was able to
sync. I used the debian source files for syncevolution (1.5.2-2) and
libsynthesis (3.4.0.47.5+syncevolution-1.5.2-1)

Big thanks to all who helped and guided so far.

My only problem is the naming of packages. So before uploading code I wanted
to sync up with you what I should do with this.

In summary the situation:
- Debian does not compile our plugins, which are in the source. After
discussing this last year, I decided we would need to provide syncevolution
for tde in packages. 
Now if someone could help me to make the packages called *-trinity it would
be great.
- I couldn't make it for some reason with the /opt/trinity path 
- Should it remove or coexist with debians or whatever distro provids
syncevolution

I would be glad to finalize this in the next 1-2 months because after this
it looks like I'll be very busy again

The work needs to be done on debian directory. I have no idea how rpm
packages are build, so for me this is out of scope

regards

PS: good thing is that I was able to build test environments for debian
which will help a lot
