Simulate the packaging build locally

Need to do this to patch warnings that are treated as errors due to the build flags set by dpkg-buildflags.

Prepare

sudo apt install debhelper
dpkg-checkbuilddeps
git clone [email protected]:aosmw/ortools_vendor.git

Build it

cd ortools_vendor
dpkg-buildpackage -d -b

Rebuild it

cd .obj-x86_64-linux-gnu
make -j10

Make fixes and make a patch

cd .obj-x86_64-linux-gnu/ortools_vendor-prefix/src/ortools_vendor/ git diff > ../../../../0001-sciperrormessage.patch

Notes dpkg-buildflags on ubuntu-22.04
