# UNITY_BUILD_BATCH_SIZE

Specifies how many source code files will be included into a `UNITY_BUILD` source file.

If the property is not set, CMake will use the value provided by `CMAKE_UNITY_BUILD_BATCH_SIZE`.

By setting it to value 0 the generated unity source file will contain all the source files that would otherwise be split into multiple batches. It is not recommended to do so, since it would affect performance.
