A few configure defines get changed: QMAKE_WASM_PTHREAD_POOL_SIZE is now QT_WASM_PTHREAD_POOL_SIZE QMAKE_WASM_TOTAL_MEMORY is now QT_WASM_INITIAL_MEMORY QMAKE_WASM_SOURCE_MAP_BASE is now QT_WASM_SOURCE_MAP_BASE device-option EMSCRIPTEN_ASYNCIFY=1 is QT_EMSCRIPTEN_ASYNCIFY=1 To create source maps for debugging. use device-option QT_WASM_SOURCE_MAP=1 Task-number: QTBUG-78647 Change-Id: If9f30cd7fb408c386d6d69b5f7b1beecf1ab44b5 Reviewed-by: Alexandru Croitor <alexandru.croitor@qt.io>
