In an effort to reduce the numbers of targets built, and consequently the repeated work and overhead of compiling boost test, a series of test programs are combined to larger modules. Every target typically has a constant cost of 3-6s, depending on the computer, just for the make to set up dependencies and for the compiler to parse and compile the testing framework and other dependencies. Each set of tests typically add very little, so significant savings are achieved by merging targets. When tested on a 2015 i5m laptop, this reduced serial, single-core compile time from ~14m45s to ~11m15s.
