Solutions to the C track exercises at exercism.io These exercises employ the Unity UTF (Unit Test Framework)
make or make test in the solution direction to build and execute the test cases.
Create a symbolic link to the vendor directory, inside the test dirs of every solution, if it doesn't already exist,
to build the solutions and test them.
This directory of Unity UTF has been factored out to avoid duplicates of the same files in every solution
cd core/1-hello-world/test/
ln -s ../../../vendor vendor
Then, for builds, change to the exercise directory
cd ..
make test
