CMake GoogleTests 找不到我的测试文件中导入的头文件

CMake GoogleTests can't find header file imported in my test file

我们(三个学生)对 CMake 很陌生。对于一个大学项目,我们必须将 GoogleTest 包含到我们的代码库中,我们遇到了很多麻烦。

我们有一个 gtest_ours.cmake 文件:

project("googletests")

enable_testing()
include(GoogleTest)

file(GLOB_RECURSE MY_SRC
        "${CMAKE_CURRENT_SOURCE_DIR}/src/*.cpp"
        # header don't need to be included but this might be necessary for some IDEs
        "${CMAKE_CURRENT_SOURCE_DIR}/src/*.h"
        EXCLUDE
        "${CMAKE_CURRENT_SOURCE_DIR}/src/MolSim.cpp"
        )

add_subdirectory(googletest)
include_directories(${gtest_SOURCE_DIR}/include ${gtest_SOURCE_DIR})

add_executable(ParticleContainerTest ${sources} ${CMAKE_CURRENT_SOURCE_DIR}/test/ParticleContainerTest.cpp )
target_link_libraries(ParticleContainerTest ${MY_SRC} gtest gtest_main gmock gmock_main)

gtest_discover_tests(ParticleContainerTest)

set_tests_properties(${noArgsTests}   PROPERTIES TIMEOUT 10)
set_tests_properties(${withArgsTests} PROPERTIES TIMEOUT 20)

CMakeLists.txt 文件中,我们只需调用:

include(gtest_ours)

我们的文件夹结构是:

main
- src
- test
- CMakeLists.txt
- others

请帮忙,我们收到以下错误:

/home/lunaticcoding/psemoldyn_groupc/MolSim-master/test/ParticleContainerTest.cpp:9:10: fatal error: ../src/ParticleContainer.h: No such file or directory
 #include "../src/ParticleContainer.h"
          ^~~~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.

gtest_ours.cmake 文件存在一些问题。出现错误是因为您还没有为 ParticleContainerTest 目标定义要包含 ParticleContainer.h 的包含目录。您只添加了 gtest_SOURCE_DIR 个目录作为包含目录。要更正此问题,请考虑在 add_executable():

之后添加此行
target_include_directories(ParticleContainerTest PRIVATE ${CMAKE_CURRENT_SOURCE_DIR}/src)

这样,src目录将是一个include目录,所以你可以修改test/ParticleContainerTest.cpp更合理的#include:

#include "ParticleContainer.h"

此外,我不确定您打算在哪里使用 ${MY_SRC} 源文件,但您不想将其包含在 target_link_libraries() 调用中。此调用应仅包括预定义的 targetslibrary 名称或链接选项作为参数;不要将源文件列表添加到此调用。我也不确定您在 add_executable() 调用中在哪里定义了 ${sources} 参数,但也许您打算将 ${MY_SRC} 放在那里。


最后,EXCLUDE 限定符不适用于 file(GLOB_RECURSE ...) 签名。但是,您可以使用 list(REMOVE_ITEM ...):

从列表 之后 中删除一个 specific 文件
file(GLOB_RECURSE MY_SRC CONFIGURE_DEPENDS
        "${CMAKE_CURRENT_SOURCE_DIR}/src/*.cpp"
        # header don't need to be included but this might be necessary for some IDEs
        "${CMAKE_CURRENT_SOURCE_DIR}/src/*.h"
)
list(REMOVE_ITEM MY_SRC ${CMAKE_CURRENT_SOURCE_DIR}/src/MolSim.cpp)
