CuTest Example Compiled with error!

I copy the example from the readme file of CuTest.
However, it compiles with error.

The following the updated version:
DETAILED EXAMPLE

Here is a more detailed example. We will work through a simple
test first exercise. The goal is to create a library of string
utilities. First, lets write a function that converts a
null-terminated string to all upper case.

Ensure that CuTest.c and CuTest.h are accessible from your C
project. Next, create a file called StrUtil.c with these
contents:

#include  <assert.h>
#include < setjmp.h>
#include <stdlib.h >
#include <stdio.h>
#include <string.h>
// The origianl version has missed the above includes
#include "CuTest.h"
    
     char* StrToUpper(char*  str) {
        return str;
    }
    
    void  TestStrToUpper(CuTest *tc) {
        char*  input = strdup(" hello world");
        char*  actual = StrToUpper(input);
        char*  expected = " HELLO WORLD";
        CuAssertStrEquals(tc, expected, actual);
    }
   
    CuSuite * StrUtilGetSuite() {
        CuSuite* suite =  CuSuiteNew();
        SUITE_ADD_TEST(suite, TestStrToUpper);
        return suite;
    }

Create another file called AllTests.c with these contents:

    #include  "CuTest.h"
    
    CuSuite*  StrUtilGetSuite();
    
    void RunAllTests(void ) {
        CuString *output = CuStringNew();
        CuSuite * suite = CuSuiteNew();
        
        CuSuiteAddSuite(suite, StrUtilGetSuite());
    
        CuSuiteRun(suite);
        CuSuiteSummary(suite, output);
        CuSuiteDetails(suite, output);
        printf(" %s\n", output->buffer);
    }
    
     int main(void) {
        RunAllTests();
    }

More detail please see its readme file.
