    build.ps1 - Assemble the US Census Java Calc add-in into build/Census.oxt

    Pipeline:
      1. unoidl-write  : idl/**.idl                -> build/types/XCensus.rdb (UNO type library)
      2. javamaker     : build/types/XCensus.rdb   -> build/gen/**.class      (Java bindings)
      3. javac         : src/**.java + bindings    -> build/classes/**.class
      4. jar           : classes + bindings        -> build/oxt/census.jar    (+ RegistrationClassName)
      5. zip           : staging tree              -> build/Census.oxt

    Requirements:
      - LibreOffice with the SDK installed (default C:\Program Files\LibreOffice,
        with the SDK under <LibreOffice>\sdk). Override with -LibreOffice.
      - A JDK (any 8+) to compile with. Resolved from -Jdk, else JAVA_HOME, else
        PATH. Output targets Java 8 bytecode (--release 8) so it runs on the
        Oracle JRE 8 that LibreOffice accepts; see docs/INSTALL.md.

    Usage:
      pwsh -File build.ps1
      pwsh -File build.ps1 -LibreOffice 'C:\Program Files\LibreOffice' -Jdk 'C:\Program Files\Android\Android Studio\jbr'
