종속성 문제 : gtest/gtest.h 해당 파일이나 디렉토리

Question

봉쥬르,

나는 현재 직장에서 ExternalProject_add를 사용하기 위해 CMake에 조금 일하고 있습니다. 그리고 googletest를 테스트하려고 할 때 나는 둘 다 테스트하려고합니다. 단위 테스트 코드를 컴파일하는 동안 문제가 발생합니다.

그래서 github의 googletest 프로젝트의 README : https://github.com/google/googletest/blob/master/googletest/README.md#incorporating-into-an-existing-cmake-project을 따르십시오.

├── CMakeLists.txt.in 
├── inc 
│ └── foo.h 
├── src 
│ └── foo.c 
└── test 
    └── test_foo.c 

내 test_foo.c 그냥 더블 라운드에 foo 함수를 테스트 : 여기

내 프로젝트 트리입니다

: 여기에 그것을 cmake 명령의 결과

#include "gtest/gtest.h" 
#include "foo.h" 

TEST(AddTest, roundValue) 
{ 
     ASSERT_EQ(roundValue(2.6),3); 
} 

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

CMake 다운로드 올바르게 googletest. 내가 include_directories의를 사용하려고

## Dependencies

내 CMakeLists.txt 파일입니다 메이크 파일과 종속은 올바른 것 같다하지만이 gtest/gtest.h의 포함에이 오류가 내 googletest의 전체 경로와 함께 많은 결과와 함께하지만 dir을 포함합니다. 그래서 생각에서

관련

Answer 1

당신이 당신의 메이크업 파일의 변경을 올바른 디렉토리 및 lib 디렉토리를 제공해야을 조금입니다.

귀하의 cmakeList 파일에 다음과 같이 변경해야합니다.

단계 : 1

googletest direcory

add_subdirectory ($ {CMAKE_BINARY_DIR}/googletest)

단계 추가 : 2 당신도 포함해야한다 lib 디렉토리 gtest

target_link_libraries ($ {PROJECT_TEST_NAME을 } foo gtest gtest_main
