1. 编译

1.1 步骤

下载源码并解压： https://github.com/google/googletest
新建build文件夹和install文件夹
使用cmake-gui来生成vs工程
在cmake-gui中设置源文件和编译文件夹路径，如下图所示
configure，设置好install路径，勾选gtest_force_shared_crt
configure
generate
Open Project
生成 INSTALL target （release和debug库切换生成）

1.2 注意事项

windows下如果不勾选"gtest_force_shared_crt"编译选项，则是生成链接MT运行时库的库，使用的时候需要设置使用程序为链接MT运行时库。

链接MD运行时库，则要勾选"gtest_force_shared_crt"编译选项

2. 使用

文件树

.
├── CMakeLists.txt
└── src
    └── main.cpp

2.1 CMakeLists.txt

cmake_minimum_required(VERSION 3.5.1)
project(cmake_gtest)

# ------------------------------------------------------------------
# gtest
# ------------------------------------------------------------------
set(GTEST "D:/deptrum/22_code/91_open_source/googletest_install/")
include_directories("${GTEST}/include")
link_directories("${GTEST}/lib")

# ------------------------------------------------------------------
# source files
# ------------------------------------------------------------------
include_directories("${CMAKE_SOURCE_DIR}/src")
AUX_SOURCE_DIRECTORY("${CMAKE_SOURCE_DIR}/src" PROJECT_SRCS)
FILE(GLOB PROJECT_HDRS ${CMAKE_SOURCE_DIR}/src/*.h ${CMAKE_SOURCE_DIR}/src/*.hpp)


# ------------------------------------------------------------------
# ${PROJECT_NAME}
# ------------------------------------------------------------------
add_executable(${PROJECT_NAME} ${PROJECT_SRCS} ${PROJECT_HDRS})
target_link_libraries(${PROJECT_NAME} debug gtestd.lib)
target_link_libraries(${PROJECT_NAME} optimized gtest.lib)

2.2 main.cpp

#include <gtest/gtest.h>

int Foo(int a, int b)
{
    if (a == 0 || b == 0)
    {
        throw "don't do that";
    }
    int c = a % b;
    if (c == 0)
        return b;
    return Foo(b, c);
}


TEST(FooTest, HandleNoneZeroInput)
{
    EXPECT_EQ(2, Foo(4, 10));
    EXPECT_EQ(6, Foo(30, 18));
}

int main(int argc, char* argv[])
{
    testing::InitGoogleTest(&argc, argv);
    RUN_ALL_TESTS();

    getchar();
    return 0;
}

使用cmake生成vs工程后，便可运行上述例子
