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包含在我们的代码库中,但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)
,从CMakeLists.txt
文件中,我们仅调用:
include(gtest_ours)
我们的文件夹结构为:
main
- src
- test
- CMakeLists.txt
- others
请帮助,我们遇到以下错误:
/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"

答案 0 :(得分:1)
gtest_ours.cmake
文件存在几个问题。由于尚未为目标ParticleContainerTest
定义包含ParticleContainer.h
的包含目录,因此引发了错误。您只添加了gtest_SOURCE_DIR
目录作为包含目录。要解决此问题,请考虑在add_executable()
之后添加以下行:
target_include_directories(ParticleContainerTest PRIVATE ${CMAKE_CURRENT_SOURCE_DIR}/src)
通过这种方式,src
目录将成为包含目录,因此您可以修改test/ParticleContainerTest.cpp
使其具有更合理的#include
:
#include "ParticleContainer.h"
此外,我不确定您打算在何处使用${MY_SRC}
源文件,但是您不想在target_link_libraries()
调用中包含此文件。该调用应仅包括预定义的目标,库名称或链接选项作为参数;不要为此调用添加源文件列表。我也不确定在${sources}
调用中您在add_executable()
参数中定义的位置,但是也许您打算将${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 ...)
从列表之后中删除特定文件:
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)
