Build deb for Debian / Ubuntu about vkvg

[stuaxo]

Thanks, thats really handy - I'll give it a try.

It might be worth surfacing this in the README.md

You may create the .deb file by running cpack command inside the build directory. On my debian, cpack is installed with the cmake package.
so the step to have your .deb:

mkdir build
cd build
cmake .. -DCMAKE_BUILD_TYPE=Release
make
cpack

then you may install the vkvg.deb file with:

dpkg -i vkvg_0.3.0.deb

If install is complaining about missing packages, you may do:

sudo apt install -f

On linux, the libc6-dev package must be installed (dependency is not configured by the .deb)

When I make a release, I try to upload a .deb package that should work on both debian and ubuntu.
