Dependencies

This program depends on TCLAP for commandline argument parsing. Check if it's available through your distribution's package manager.

Googletest and Googlebench are used for unit testing and benchmarking respectively; these are automatically downloaded and compiled as part of the build process.

Installation and usage:

Compilation should be as simple as make (or make all); you will likely want to set the CMAKE_BUILD_TYPE option to Release to enable the maximum optimization level (ex: CMAKE_BUILD_TYPE=Release make all).

After the build is complete, run the binary with --help for usage information.

Thanks to the Wordler dude for making the game. Thanks to Donald Knuth for generally being a baller, but specifically for his algorithm to solve Mastermind, which I relied on heavily while writing this program.
