概述

集成GTest框架

在C++工程的third_party里面新建gtest目录

image-20220623111608308

下载源码：https://github.com/google/googletest/releases

现在最新的版本是v1.11.0

下载源码完成之后，进行编译gtest

使用cmake生成makefile

1
cmake ../googletest -DCMAKE_INSTALL_PREFIX=./install

编译出错

CMake Error at CMakeLists.txt:134 (set_target_properties):
  set_target_properties called with incorrect number of arguments.

这个原因是：是因为没有指定gtest的版本号，我们在googletest的根目录下的CMakeLists.txt文件中增加一行：

1
set(GOOGLETEST_VERSION 1.11.0)

重新执行这个脚本

结果通过

执行编译生成静态库

然后将我们的生成产品拷贝到我们的工程：

综上完整脚本如下：

编译Linux版本

mkdir gtest-build
cd gtest-build 
cmake ../googletest -DCMAKE_INSTALL_PREFIX=./install
make && make install

编译Qnx版本

cd gtest-build 
cmake ../googletest -DCMAKE_INSTALL_PREFIX=./install  -DCMAKE_TOOLCHAIN_FILE=./arm-unknown-nto-qnx700eabi.toolchain.cmake
make && make install

编写Cmake依赖文件
