如何在C ++ Qt Creator中使用库

Question

I downloaded a library for processing DicOM FILES .
The tree of library is :

|--include
        |-----dicom.h
        |-----dicomcfg.h
|--lib
     |--------dicomsdl.lib

But I do not know how to use and built-in Qt Creator .
If anyone can help me I will be very grateful.

I'll assume you use qmake as your build system. To link your "external" library you need following changes in your .pro file:

#path to includes directory of your library, qmake will try to find includes there
INCLUDEPATH += /path/to/library/include

#path to pre-compiled library directory
LIBS += -L/path/to/precomp/library

#link your pre-compiled library, -l<library name> w/o .so, .a, .lib, lib- prefix
LIBS += -ldicomsdl

Maybe you'll need to build the library from source with your compiler. There could be some troubles if compilers don't match.
