在GitHub操作下运行时，将多个cmake库目标合并为单个目标失败

我正在尝试使用现代cmake构建系统建立持续集成工作流GitHub。在这个构建系统中，我需要找到两个外部库，一个C和Fortran版本。因为这些库不是内置的FindLIBRARY，所以我必须创建自己的库。我还想设置它，以便两个库可以作为单个目标链接

find_path (LIBRARY_INCLUDE_DIR
           NAMES library.h)
mark_as_advanced (LIBRARY_INCLUDE_DIR)

find_library(LIBRARY_C_LIBRARY
             NAMES c_version)
mark_as_advanced (LIBRARY_C_LIBRARY)
find_library(LIBRARY_Fortran_LIBRARY
             NAMES fortran_version)
mark_as_advanced (LIBRARY_Fortran_LIBRARY)

include (FindPackageHandleStandardArgs)
find_package_handle_standard_args (LIBRARY
                                   REQUIRED_VARS LIBRARY_C_LIBRARY LIBRARY_Fortran_LIBRARY     LIBRARY_INCLUDE_DIR

if (LIBRARY_FOUND)
    set (LIBRARY_INCLUDE_DIRS ${LIBRARY_INCLUDE_DIR})
    set (LIBRARY_LIBRARIES "${LIBRARY_C_LIBRARY} ${LIBRARY_Fortran_LIBRARY}")

    if (NOT TARGET LIBRARY::LIBRARY_C)
        add_library (LIBRARY::LIBRARY_C UNKNOWN IMPORTED)
        set_target_properties (LIBRARY::LIBRARY_C PROPERTIES
                               IMPORTED_LOCATION ${LIBRARY_C_LIBRARY}
                               INTERFACE_INCLUDE_DIRECTORIES ${LIBRARY_INCLUDE_DIR})
    endif ()
    if (NOT TARGET LIBRARY::LIBRARY_Fortran)
        add_library (LIBRARY::LIBRARY_Fortran UNKNOWN IMPORTED)
        set_target_properties (LIBRARY::LIBRARY_Fortran PROPERTIES
                               IMPORTED_LOCATION ${LIBRARY_Fortran_LIBRARY}
                               INTERFACE_INCLUDE_DIRECTORIES ${LIBRARY_INCLUDE_DIR})
    endif ()

    if (NOT TARGET LIBRARY::LIBRARY)
        add_library (LIBRARY::LIBRARY INTERFACE IMPORTED)
        target_link_libraries (LIBRARY::LIBRARY INTERFACE LIBRARY::LIBRARY_C LIBRARY::LIBRARY_Fortran)
    endif ()
endif ()

然后，当我去导入并链接到我自己的目标

cmake_minimum_required (VERSION 3.14)

project (my_project C Fortran)

set (CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH};${CMAKE_CURRENT_SOURCE_DIR}/cmake)
find_package (LIBRARY MODULE REQUIRED)

add_library(my_library STATIC)

... # Add target sources here.

if (LIBRARY_FOUND)
    target_link_libraries (my_library INTERFACE LIBRARY::LIBRARY)
endif ()

然后我在某个可执行文件中使用我的库

add_executable (my_program)
target_link_libraries (my_program my_library)

---

当我在本地开发机器（MacOS 10.14.6）上运行它时，一切都正常

my_程序

拾取所有编译定义，包括在链接目标上设置的目录和编译器标志属性。然而，当我尝试将它作为GitHub操作（ubuntu最新版本）运行时，它失败了。当我使用

make VERBOSE=1

构建时，我可以看到

库\u INCLUDE\u DIR

属性丢失。这两台机器运行的是同一版本的cmake。

结果是修复程序要更改

if (LIBRARY_FOUND)
    target_link_libraries (my_library INTERFACE LIBRARY::LIBRARY)
endif ()

到

---

将其链接为

接口

，意味着链接到

我的库

的东西会看到include目录，但

我的库

源没有。

“我可以看到库的include\u DIR属性丢失。”-因此，这是脚本中失败的第一行。此问题与标题中所述的“梳理CMake库目标”有何关系？

find_path

定义了

library_INCLUDE_DIR

变量。是的，第一行

find_path

定义了

library_INCLUDE_DIR

变量。如果未找到头文件，则变量设置为

-NOTFOUND

。“我可以看到

LIBRARY\u INCLUDE\u DIR

属性缺失。”你是指最新的案例，对吗？它发现标题很好。哦，然后我错误地理解了你的问题陈述——“我可以看到LIBRARY\u INCLUDE\u DIR属性缺失。”。你能详细说明一下吗？这是否意味着

LIBRARY\u INCLUDE\u DIR

的值没有传递给编译器？如果是，您是否尝试过（出于调试目的）与单独的目标链接是否有效：

目标链接库（my_library INTERFACE library:：library_C library:：library_FORTRAN）

？

if (LIBRARY_FOUND)
    target_link_libraries (my_library PUBLIC LIBRARY::LIBRARY)
endif ()
