Command Explanations

--buildtype=release: Specify a buildtype suitable for stable releases of the package, as the default may produce unoptimized binaries.

-Ddemos=false: This switch disables building the demo programs because building plplay is currently broken.

-Dtests=true: This switch enables building the code necessary to run the tests.
