Removed boost signals from CMakeLists.txt

[bionade24]

With boost=>1.69 there signals isn't available anymore. As it's not necessary, it should be removed to be compatible to all boost versions.

Same issue here: ros/ros_comm#1580

@jonbinney if you could take a look at this it would be much appreciated!

[jonbinney]

@acxz thanks for the reminder! I tried this out and it doesn't break anything. @bionade24 thank you!

[bionade24]

When can we expect a new release of this repo?

[jonbinney]

@bionade24 what ros distro are you using?

[bionade24]

I'm maintaining the melodic AUR packages.

Let me try doing a melodic release now

Thanks

I just released version 1.7.7 of laser_asembler and version 1.8.7 of laser_assembler into melodic.

Thanks! No I can remove the patches out of the packages.
