I am facing an error while I am trying to build my project using cmake.
I manually downloaded and install gtest on my pc (i.e. gtest header files are available in /usr/include) and libs such as gtest, gtest_main in /usr/lib)
Below is the code of my projects main function. (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;
}
When I compiled this file separately using the below command, it is working!!
g++ eNB_scheduler_test.cpp -L /usr/lib/ -lgtest -lgtest_main -pthread -std=c++11
But, when I tried to include this in my projects CMake file, it is showing me an error.
# lte-softmodem is both eNB and UE implementation

Edit:
I have edited the question with the error logs, and MAKE output while compiling the file. Thanks in advance for spending your time.
This is how I personally include Google Test in a clean way:
# To prevent overriding the parent project's compiler/linker settings on Windows.
if(WIN32)
set(gtest_force_shared_crt ON CACHE BOOL "" FORCE)
endif()

You can also use the FindGTest.cmake module with the find_package function make sure to define the environment variable GTEST_ROOT. If these methods would work while your method does not, then it could be your linker settings through cmake(check for syntax errors).
