Benchmarks

TCM provides a single function to benchmark using Google Benchmarks.

tcm_benchmarks (
        [NAME <name>] 
        FILES <file>...
        [LIBRARIES <target> ...]
)

If no NAME is provided, then sources files are added to default target ${PROJECT_NAME}_Benchmarks. Otherwise, a target with provided name is created.

Every target is linked with benchmark::benchmark_main, so no need to provide a main function. Multiple calls with the same target will just add sources files to the target.

Benchmark target can also be linked with LIBRARIES targets

Example

tcm_benchmarks(FILES benchmark_1.cpp benchmark_2.cpp) # Added to default target `${PROJECT_NAME}_Benchmarks`
tcm_benchmarks(NAME my_target FILES benchmark_1.cpp benchmark_2.cpp) # Added to target `my_target`

If you wish to override Google Benchmarks, do the following once before calling tcm_benchmarks:

tcm_setup_benchmark(GOOGLE_BENCHMARK_VERSION "vX.X.X")
