ortools-with-cmake

How-to demonstrating integration of binary OR-tools for C++ package inside of a cmake project.

Install or-tools from binary

Follow the steps here.

Build this repo

Note: this has only been tested on Ubuntu 18.04 but should work on other distros / OSes.

cd {path-to-this-repo}
mkdir build && cd build
cmake -DORTOOLS_ROOT:STRING="{path-to-ortools-root-dir}" ..
make

You'll see some warnings most likely.

Test the build

The test executable built in the previous step uses the toy example provided by Google from here.

Run the test:

./test-app

You should see the following output:
