Improve test build process #5
Description
The current model to compile the testing suite is to include each test file in a single file tests.cpp. This file is then compiled instead of compiling and linking each test file separately. Compiling a single file which includes all test files is not ideal because any time a test is changed the entire test suite must be rebuilt. However, because draft is a header-only library, each compiled test object file contains all of draft's definitions, resulting in duplicate definition errors on linking.
This issue is to track progress on reaching a better solution to building tests for draft.
