:-1: error: Project ERROR: Could not find feature open62541.

Hi at all, after some days of warning, finally can compile qtopcua project. I'm over debian12, so I've install gcc9, g++9, clang9 qt5.15.2 and so all necessary for compile over qt5.15.2 .... perhaps I use qtcreator 9 now instead new qtcreator14. I've two or 3 machine working on qt5.15, qtcreator9 and gcc9 (all ubuntu and mint) .... so not understand because not work on debian12, precisely on LMDE6 kernel 6.6

About open62541, was unable to add ppa for install libopen62541 .... seems key of atp is not right for debian12 system..... but can dowload qtopcua and compile it on qtcreator with 2 warning on qhash and nothing other .....

Any how when try to run my old project that use qtopcua, obtain these error:

:-1: error: Project ERROR: Could not find feature open62541.

I use clean environment flag on qtcreator, I ser gcc9, g++9 and clang9 as default .... not undersatnd why open62541.pri was not find from qmake or cmake process ....

any suggest was appreciate

Now I change version with fresh install ... use qtcreator14, qt6.6.3 .... install open62541 from git using doc of open62541 guy, I install qtopcua using "how to" of guy of basyscom .... add necessary INCLUDEPATH and LIBS on .pro file .... and all work.
Only if add a switch on .pro file for system-open62541 these fails with "system-open62541" file not find. If leave these switch all work ..... ps: on debian 12 is not possible to install libopen62541-dev from repo .....

Have you installed it, though? You need to install in order for other projects to see this. Or alternatively, you can include() the .pri file in your project.

these is done ... because my qt install are in "home folder". Any how I've install it any way ..... so in my /QT/5.15.2/gcc_64/include thare are qtopcua forlder .... but nothing to do ..... same error
