Can you please tell me where exactly do you see this?

Regarding the project configuration I have learned that:

- deleting the build dir is more effective to reflect changes to cmake configuration
- Inside CMakeCache.txt OPENSSL_ROOT_DIR was set to UNINITIALIZED and I have manually set it to PATH
- Inside CMakeCache.txt I have defined OPENSSL_INCLUDE_DIR to c:\Qt-Utils\openssl\include

After this changes, the cmake ran successful and I was able to build and run the example with my custom kit.

This seems like little quirks but makes me feel that CMake and Qt is still black magic! :)

Any advice based on this feedback?

Thank you!

Best regards,

Nuno
