Additional import path used to resolve QML modules

Episode 1: Additional import path used to resolve QML modules in Qt Creator's code model

# Additional import path used to resolve QML modules in Qt Creator's code model
QML_IMPORT_PATH =$( ... )

Episode 2: Avoid of Using QQmlEngine::addImportPath() in main.cpp file:

# Use QML2_IMPORT_PATH variable to avoid using QQmlEngine::addImportPath() in main.cpp

QML_IMPORT_PATH=$(QML2_IMPORT_PATH)
