I'm having a hell of a time finding documentation which clearly explains how to use a static library in Qt Creator.
I've created and compiled my static library using Qt Creator (New=>Projects\C++ Library=>Set type to "Statically Linked Library"). It compiles and spits out a ".a file".
The problem I encounter is when I try to use the library. I have another project that would like to use it (#include files in the library, etc) but I don't know the proper way to link with the library or include files from the library.
LIBS += -L[path to lib] -l[name of lib]
Note! that filename of lib: lib[nameOfLib].a and you have to pass only original part -l[nameOfLib]
