Installing Problems with Qt OPC UA 5.15.0

[Benoit11564]

Hello,

I would like to have help to solve my issues regarding the installation of QT OPC UA 5.15.0.
I have followed the steps described in the website https://blog.basyskom.com/building-qt-opc-ua-with-open62541. When I execute the command linemingw32-make, I have the following error :
fatal error: openssl/asn1.h: file or path not found
59 | #include <openssl/asn1.h>
| ^~~~~~~~~~~~~~~~
I have finally "solved" this problem by adding manually the include of openssl in the build folder of qtopcua.
However, the command mingw32-make install results to the following error :
..\..\build\lib\pkgconfig\Qt5OpcUa.pc: No such file or directory

Can someone help me please?

Thank you very much!
