CMake Cookbook

Getting ready

We will keep main.cpp, sum_integers.cpp, and sum_integers.hpp unchanged from the previous recipes, but will update the test.cpp source code, as follows:

#include "sum_integers.hpp"#include "gtest/gtest.h"#include <vector>int main(int argc, char **argv) {  ::testing::InitGoogleTest(&argc, argv);  return RUN_ALL_TESTS();}TEST(example, sum_zero) {  auto integers = {1, -1, 2, -2, 3, -3};  auto result = sum_integers(integers);  ASSERT_EQ(result, 0);}TEST(example, sum_five) {  auto integers = {1, 2, 3, 4, 5};  auto result = sum_integers(integers);  ASSERT_EQ(result, 15);}

As indicated in the preceding code, we chose to explicitly place neither gtest.h nor other Google Test sources in our code project repository, but will download them at ...
