Question

审议以下<代码>CMakeLists.txt文档:

add_subdirectory(execA)
add_subdirectory(libB)

install(TARGETS execA libB
        RUNTIME DESTINATION bin
        LIBRARY DESTINATION lib
        ARCHIVE DESTINATION lib)

我有以下错误:

install TARGETS given target "execA" which does not exist in this
  directory

www.un.org/Depts/DGACM/index_spanish.htm 有自己的<代码>CMakeList.txt文档,并位于> 项目目录以及建筑名录Im 每天cmake/code>(cmake .):



project
  |------ CMakeList.txt (the one with the code)
  |----execA
  |      - .cpp, .hpp and CMakelist.txt
  |----libB
  |      - .cpp, .hpp and CMakelist.txt
  |---- lib
  |---- bin
  ---- build (where I´m commanding: $ cmake ..


我如何纠正这一错误?

http://cmake.org/Bug/view.php?id=144"rel=“noreferer”>.this bugreport,install(TARGETS) 指挥流动只接受同一目录内开列的目标。

因此,您要么需要将<代码>add_library()打电话到最高层名录,要么将install(TARG)打电话到每个目标类别,然后将每一条带入相应的子。
自CMake 3.13 install(TARGETS)can work, 即便其他名录设定了目标。 install(TARGETS)可安装其他名录设定的目标。在使用这种跨直接分层安装规则时,从子站运行<代码>makestal><>(或类似)将无法保证其他名录的目标具有最新性。

Even though it would help seeing the CMakeLists.txt files contained in the subdirectories, I guess they contain add_executable and/or add_library statements to create your stuff.
Also, because of your example, I guess you are using the same name of your directories for your targets.
That said, you should know that symbols defined in a CMakeLists.txt file in a subdirectory are not visible by default within the context of the CMakeLists.txt file in the parent directory. Because of that, you should rather move your install statements within the CMakeLists.txt files within your subdirectories.
This should solve the problem, if my thoughts were right. Otherwise, I strongly suggest you to post in your question also the content of the other files above mentioned.

Anyway, the error is quite clear.
The file that contains the install statement for the target named X does not contain a target creation statement (add_executable and the others) that gives birth to that target, so it goes on saying that that target does not exist in that directory.

这似乎仍然是CMake 3.11的痛苦点。

在我们的代码基中,我们有许多目标被分局界定,需要建立配置不同和(可能重叠)目标组合的安装器的配置。

我的解决办法是:


Before calling add_subdirectory in your root CMakeLists.txt file, create a GLOBAL property with the names of the target(s) you want to include in your installer.
Wrap target creation functions (add_executable, etc.) in your own custom functions. Within those functions check if the target is present in the global property, and invoke install accordingly.


这种做法使你能够集中配置安装装置。

此外,为了支持多台安装装置的建立,我们把我们的全球清单和其他安装物放在单独的剪辑档案中。当我们援引<代码>cmake时,我们把安装装置组合CMake文档的名称当作一条指挥线。我们的根源是CMakeList。 txt文档仅打电话include。

我认为你可以这样做:


add_subdirectory(execA)
add_subdirectory(libB)

function(install_all_targets DIR)
    get_property(TGTS DIRECTORY "${DIR}" PROPERTY BUILDSYSTEM_TARGETS)
    foreach(TGT IN LISTS TGTS)
        message(STATUS "Target: ${TGT}")
        install(TARGETS ${TGT}
                RUNTIME DESTINATION bin
                LIBRARY DESTINATION lib
                ARCHIVE DESTINATION lib)
    endforeach()

    get_property(SUBDIRS DIRECTORY "${DIR}" PROPERTY SUBDIRECTORIES)
    foreach(SUBDIR IN LISTS SUBDIRS)
    install_all_targets("${SUBDIR}")
    endforeach()
endfunction()

install_all_targets(.)
