CMake如何正确包含我自己的标题？

Question

我正在与ros合作，现在我想编写自己的单元测试。但是我正在努力。也许你对我有个建议？还是一个解决方案？

my structure:
-catkin_ws
--build
--install
--src
----project1
----CMakeLists.txt
----package.xml
------include
--------prime_tables.h
--------sample1.h
------src
--------sample1.cpp
------tests
--------sample1_unittest.cpp

我的cmakelist.txt：

cmake_minimum_required(VERSION 2.8.3)
project(project1)

find_package(catkin REQUIRED COMPONENTS roscpp rostest rosunit)
find_package(sample1)



catkin_package(
   INCLUDE_DIRS include
   LIBRARIES ${PROJECT_NAME}
   CATKIN_DEPENDS roscpp rostest
   DEPENDS  )
include_directories(include ${catkin_INCLUDE_DIRS})


if (CATKIN_ENABLE_TESTING)
  catkin_add_gtest(project1 tests/sample1_unittest.cpp)

  add_executable(add_test tests/sample1_unittest.cpp)
  add_library(add include/sample1.h src/sample1.cpp)
  target_link_libraries(add_test ${catkin_LIBRARIES})
  target_link_libraries(add_test gtest)
  target_link_libraries(add_test prime_tables)
  target_link_libraries(add_test sample1)
endif()

我收到此错误：

[87%] Linking CXX exectuable

/usr/bin/ld -lprime_tables cannot find
/usr/bin/ld -lsample1 cannot find

是什么问题？您提到它，我对CMake不太熟悉。

Answer 1

在sample1.cpp中是您要测试的库，并且要创建一个链接到该库并运行单元测试的可执行文件？

一些基本的cmake信息：add_library，add_executable和target_link_libraries的第一个参数是库/可执行文件的名称。因此，如果您将链接库指定为此库或可执行文件，则必须再次使用此名称。

并在此处查看更多信息：http://wiki.ros.org/catkin/CMakeLists.txthttp://docs.ros.org/jade/api/catkin/html/howto/format2/gtest_configuration.html

我的猜测是，您想要这样的cmake：

cmake_minimum_required(VERSION 2.8.3)
project(project1)

catkin_package(
  INCLUDE_DIRS include
  LIBRARIES ${PROJECT_NAME}
  CATKIN_DEPENDS roscpp rostest
  DEPENDS
)
include_directories(include 
  ${catkin_INCLUDE_DIRS}
)

add_library(${PROJECT_NAME}_sample1 
  src/sample1.cpp
)
target_link_libraries(
  ${PROJECT_NAME}_sample1
  ${catkin_LIBRARIES}
)

if (CATKIN_ENABLE_TESTING)
  catkin_add_gtest(${PROJECT_NAME}_test 
    tests/sample1_unittest.cpp
  )
  target_link_libraries(${PROJECT_NAME}_test 
    ${PROJECT_NAME}_sample1
    ${catkin_LIBRARIES}
  )
endif()
