If you are using QT Creator on Windows, you are also compiling with the 
MinGW gcc compiler. This compiler produces static libraries with a .a 
extension, as in 'nix operating systems. There are no settings that 
cause MinGW gcc to create a static library with the .lib extension. It 
is the Microsoft compilers that produce static libs with a .lib extension.
Gcc libraries traditionally have names like libfoo.a. To include 
libfoo.a in your project just add a line
LIBS += -Lpathtolib -lfoo
