CMake GoogleTests在我的测试文件中找不到导入的头文件

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

本文关键字:文件 找不到 导入 CMake 我的 测试 GoogleTests      更新时间:2023-10-16

我们(三个学生(是CMake的新手。对于一个大学项目,我们必须将GoogleTest纳入我们的代码库,而我们在这方面遇到了很多麻烦

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,我们只调用:

include(gtest_ours)

我们的文件夹结构是:

main
- src
- test
- CMakeLists.txt
- others

请帮助,我们得到以下错误:

/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.
CMakeFiles/ParticleContainerTest.dir/build.make:62: recipe for target 'CMakeFiles/ParticleContainerTest.dir/test/ParticleContainerTest.cpp.o' failed
make[2]: *** [CMakeFiles/ParticleContainerTest.dir/test/ParticleContainerTest.cpp.o] Error 1
CMakeFiles/Makefile2:144: recipe for target 'CMakeFiles/ParticleContainerTest.dir/all' failed
make[1]: *** [CMakeFiles/ParticleContainerTest.dir/all] Error 2
Makefile:140: recipe for target 'all' failed
make: *** [all] Error 2

gtest_ours.cmake文件存在几个问题。由于您尚未将ParticleContainerTest目标的包含目录定义为包含ParticleContainer.h,因此引发了错误。您只添加了gtest_SOURCE_DIR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,因此您可以修改test/ParticleContainerTest.cpp以获得更合理的#include:

#include "ParticleContainer.h"

此外,我不确定您打算在哪里使用${MY_SRC}源文件,但您不希望在target_link_libraries()调用中包含此文件。此调用应仅包括预定义的目标名称或链接选项作为参数;不要将源文件列表添加到此调用。我也不确定您在add_executable()调用中在哪里定义了${sources}参数,但也许您想把${MY_SRC}放在那里。


最后,EXCLUDE限定符不适用于file(GLOB_RECURSE ...)签名。但是,您可以在之后使用list(REMOVE_ITEM ...):从列表中删除特定的文件

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)
