CMake gtest 'Error running test executable' Result:24

Question

I have a project and have the following project structure: -project-root

--src
----Main.cpp
----Room.cpp
----Room.h
----xxx.cpp
----xxx.h
--Tests
----Tests.cpp
----CMakeLists.txt

My CMakeList.txt:

cmake_minimum_required(VERSION 3.14)
enable_testing()
project(practical_08_11_Tests)
set(CMAKE_CXX_STANDARD 14)
#Setup GoogleTest Unit Testing Framework
include(FetchContent)
FetchContent_Declare(
        googletest
        URL https://github.com/google/googletest/archive/refs/tags/release-1.11.0.zip
)

set(gtest_force_shared_crt ON CACHE BOOL "" FORCE)
FetchContent_MakeAvailable(googletest)


#Get ABSOLUTE PATH of SRC dir

message("SRC:${src}")

add_executable(
        Test
        Tests.cpp
  )
target_link_libraries(
        Test
        SRC
        gtest_main
)

include(GoogleTest)
add_test(GoogleTest Test)
gtest_discover_tests(Test)

When I run the build, it gives me the following error, I tried to search on the internet and haven't found solutions yet.

[ 45%] Built target gtest
[ 62%] Built target SRC

The error has gone if I remove the SRC library in the target_link_libraries, I tried to remove this SRC lib and add the files in the add_executables() section but it produce the same error.

Test Source Code:

#include <gtest/gtest.h>
#include "Room.h"
#include "RoomFactory.h"
TEST(GetFreeRoomTest_IsOccupied,RoomTest)
{
    //Arrange
    RoomFactory& factory=RoomFactory::getInstance();
    //Act
    Room * room= factory. occupyAFreeRoom(Comfortable);
    //Assert
    EXPECT_FALSE(room->roomStatus==Empty);
}```



 This is making me dying. Pls, help.

Answer 1

Problem solved, there are non-project files in ${sources} and included the cmake-build-debug files used for debugging.
