A container with the build tools can be built. This container can be inherited, build the app, and then a new container made which copies the app over.

This will save installing build tools every time you want to build the app.

However, the build container will be quite large.

Generally we want to see all of the test output (each specific test in each test group).

Currently, the test groups are run with make test but only displays an aggregate output (pass/fail #) of each test group (instead of each test from each test group). This is problematic for figuring out which individual test failed.

currently the tests run as part of the Docker build process.

Ideally a testing docker image could be generated that has the compiled code ready for tests. This will require modifying the CMakeLists.txt to build the tests (but not run them) and then copy the test files into the new container.

cmake -G Ninja .. and cmake --build ./
