CMake 和 CTest：如何使目标“每晚”实际构建测试

这是一个众所周知的问题，执行 make "test" 不会构建所讨论的测试这里。正如所建议的，这个问题可以通过人工目标“检查”来部分解决。我想知道当我调用“make Nightly”时如何强制构建测试。

到目前为止我所做的：

  add_custom_target(buildtests)
  add_custom_target(check COMMAND "ctest")
  add_dependencies(check buildtests)
  add_dependencies(Nightly buildtests)

  add_dependencies(buildtests Test1)
  ...
  add_dependencies(buildtests TestN)

现在“make check”构建并运行测试，但“make Nightly”

构建测试
将存储库更新为 CTEST_NIGHTLY_START_TIME
构建所有其他目标
运行（现已过时）测试

It's a well known problem that executing make "test" doesn't build the tests as discussed here. As suggested, the problem can be partly solved with the artificial target "check". I want to know how I can force building of tests when i call "make Nightly".

What I've done so far:

  add_custom_target(buildtests)
  add_custom_target(check COMMAND "ctest")
  add_dependencies(check buildtests)
  add_dependencies(Nightly buildtests)

  add_dependencies(buildtests Test1)
  ...
  add_dependencies(buildtests TestN)

Now "make check" builds an runs the tests, but "make Nightly"

builds the tests
updates the repo to CTEST_NIGHTLY_START_TIME
builds all other targets
runs the (now outdated) tests

你是对的，这实际上是我自己的调用错误：

add_subdirectory(test EXCLUDE_FROM_ALL)

解决方案是将其更改为

if(LEAVE_TEST_IN_ALL_TARGET) 
  add_subdirectory(test) 
else() 
  add_subdirectory(test EXCLUDE_FROM_ALL) 
endif()

然后调用

cmake ${SRC_DIR} -DLEAVE_TEST_IN_ALL_TARGET=ON make Nightly

You're right, it was actually my own fault for calling:

add_subdirectory(test EXCLUDE_FROM_ALL)

The solution was to change it to

if(LEAVE_TEST_IN_ALL_TARGET) 
  add_subdirectory(test) 
else() 
  add_subdirectory(test EXCLUDE_FROM_ALL) 
endif()

and then call

cmake ${SRC_DIR} -DLEAVE_TEST_IN_ALL_TARGET=ON make Nightly

如果您查看输出，

cmake --help-command add_custom_target

它提到了 ALL 参数，“如果指定了 ALL 选项，则表明应将此目标添加到默认构建目标，以便每次都会运行它”。您需要将此参数添加到自定义目标中，并且 Nightly 目标运行 make 来构建默认构建目标中的所有内容。因此，应该执行以下操作，

add_custom_target(buildtests)

您的另一个选择是编写自定义 CTest 脚本，它可以让您对项目的构建和测试进行更细粒度的控制。

If you look at the output of,

cmake --help-command add_custom_target

It mentions the ALL argument, "If the ALL option is specified it indicates that this target should be added to the default build target so that it will be run every time". You would need to add this argument to your custom target, and the Nightly target runs a make to build everything in the default build target. So the following should do it,
