# AUTOGEN_PARALLEL

Number of parallel `moc` or `uic` processes to start when using `AUTOMOC` and `AUTOUIC`.

The custom <origin>_autogen target starts a number of threads of which each one parses a source file and on demand starts a `moc` or `uic` process. `AUTOGEN_PARALLEL` controls how many parallel threads (and therefore `moc` or `uic` processes) are started.

- An empty (or unset) value or the string `AUTO` sets the number of threads/processes to the number of physical CPUs on the host system.
- A positive non zero integer value sets the exact thread/process count.
- Otherwise a single thread/process is started.

By default `AUTOGEN_PARALLEL` is initialized from `CMAKE_AUTOGEN_PARALLEL`.
