gtest can provide a main function but something this might conflict if you just want to use the comparison macros. Added a new variable in the meson build system gtest_nomain_dep which brings in the macros but not the main function. This can be linked against without having to worry about main function conflicts.
we will use meson as the build system for this project. Added a rough outline of this which builds source, libraries, and links them to tests (along with the google test library for testing). meson will be setup and compiled with ./mk.
