To be a good citizen, and to work with the latest TBB library, SMTK has enabled QT\_NO\_KEYWORDS builds. In practice, this means that SMTK plugins and apps should adopt this change as well. The required changes are simple:

- For source files that use QT, replace:
  - `slots:` with `Q_SLOTS:`
  - `signals:` with `Q_SIGNALS:`
  - `emit` with `Q_EMIT`
  - `foreach` with `Q_FOREACH`

- In CMake code for each QT using lib/plugin/app, so the compiler will enforce:
  - `target_compile_definitions(myTarget PRIVATE QT_NO_KEYWORDS)`
  - This can only be done if all used headers are compliant.
