SOLUTION


I solved it the error with QApplication by linking the QT_LIBRARIES with the test files with the following code





target_link_libraries( alkusertest Alkuser alkimia ${QT_QTCORE_LIBRARY} ${QT_QTTEST_LIBRARY} ${QT_LIBRARIES} )
target_link_libraries( alkinvoicetest Alkinvoice alkimia ${QT_QTCORE_LIBRARY} ${QT_QTTEST_LIBRARY} ${QT_LIBRARIES} )
target_link_libraries( alkpaymenttest Alkpayment alkimia ${QT_QTCORE_LIBRARY} ${QT_QTTEST_LIBRARY} ${QT_LIBRARIES} )
