one more time ... #include question ( Linux)

[Anonymous_Banned275]

This is result of "add library" to subpro .pro file

unix:!macx: LIBS += -L$$OUT_PWD/../A_DEC17_BT_Utility_Library/ -lA_DEC17_BT_Utility_Library

INCLUDEPATH += $$PWD/../A_DEC17_BT_Utility_Library
DEPENDPATH += $$PWD/../A_DEC17_BT_Utility_Library

now I have to add (#include )  such library header to 
.pro header where the library is used 

Usually intelisense  helps - intuitive - , but 
what other tool is helpful ??


I am getting multiple intelisense entries and  no mater which one I select I still cannot access the library- compiler fails . 

Thanks for reply, help is much appreciated.
