Adding a C library is giving this error when trying to compile

This is not the first time I have this type of problem when trying to use libraries in my programs. I configured the folders in the linker / compiler, but it is not working. I'm using Code Blocks, but I already tried it on Dev-C ++ and Netbeans, and I also had problems.
The library I'm using is this and the program I tried to compile and this:
#include <stdlib.h>
#include <iup.h>
int main(int argc, char **argv)
{
IupOpen(&argc, &argv);
IupMessage("Hello World 1", "Hello world from IUP.");
IupClose();
return EXIT_SUCCESS;
}
Update:
I'm using Windows 10x64 with the MingW compiler.
I followed the step-by-step, put the library in the compiler folder and included the header file in both the project hierarchy and the compiler configuration. Although this is giving this error:
