gtest编译期间出现Cmake错误-gtest/internal/gtest类型util.h:732:25:错误:需要
Cmake Error during gtest compilation - gtest/internal/gtest-type-util.h:732:25: error: expected type-specifier
我在尝试使用cmake构建项目时遇到错误
我在电脑上手动下载并安装了gtest(即gtest头文件在/usr/include中可用)和库，如gtest、gtest_main在/usr/lib中)
下面是我项目的主要功能代码。(lte_softmodem_test.cpp)
#include <gtest/gtest.h>
#include <iostream>
using namespace std;
TEST(sample, sample2){
}
int main(int argc, char **argv)
{
cout << "This is test" << endl;
testing::InitGoogleTest(&argc, argv);
return RUN_ALL_TESTS();
return 0;
}
当我使用下面的命令单独编译这个文件时，它正在工作！！
g++ eNB_scheduler_test.cpp -L /usr/lib/ -lgtest -lgtest_main -pthread -std=c++11
但是，当我试图将其包含在我的项目CMake文件中时，它显示了一个错误。
CMake文件：(CMake文件有点大，所以我只在试图编译这个文件的地方包含了几行)
# lte-softmodem is both eNB and UE implementation

编辑：
我已经用错误日志编辑了这个问题，并在编译文件时进行了输出。提前感谢您花费时间。
这就是我个人如何以一种干净的方式包含谷歌测试：

您还可以将FindGTest.cmake模块与find_package函数一起使用，确保定义环境变量GTEST_ROOT。如果这些方法可以工作，而你的方法不可以，那么它可能是你通过cmake的链接器设置(检查语法错误)。
