Hps_qt_sandbox.exe does not have an entry point

I have built the hps_qt_sandbox sample application. When I run the executable it complains there there is no entry point to the executable. main.cpp gets compiled and linked.

I ran the qmake with -tp vc hps_qt_sandbox.pro to create a visual studio project file. Then devenv was able to compile all cpp files and build the executable.

Please help sort this out!
Thank you.

I found my issue. The problem was the app was loading QT DLLs from the HOOPS lib folder while I was using a newer QT libs to link. Once I pointed to the correct Qt DLLs app is working good.
