Question

我有一个包含三个二进制文件的项目，我正在使用CMake构建。一个是可执行文件，两个是DLL。 CMake只有一个DLL被自动复制到可执行文件的构建目录中;另一个不是。自动复制的DLL是C ++ / CLI DLL，而不是本机DLL，但链接到expat，它是我项目外部的DLL。

下面是四个CMakeLists.txt文件（名称已更改）。

cmake_minimum_required(VERSION 3.5 FATAL_ERROR)
project(my_project VERSION 0.1)

find_package(EXPAT REQUIRED)
add_library(expat INTERFACE IMPORTED)
set_target_properties(
    expat
    PROPERTIES
    INTERFACE_INCLUDE_DIRECTORIES "${EXPAT_INCLUDE_DIRS}"
)

add_subdirectory(my_exe)
add_subdirectory(my_managed_dll)
add_subdirectory(my_dll_using_expat)

my_exe /的CMakeLists.txt：

set(
    SOURCES
    ...
)

add_executable(my_exe ${SOURCES})

target_compile_definitions(my_exe PRIVATE _UNICODE)
target_include_directories(
    my_exe
    PRIVATE "${CMAKE_CURRENT_BINARY_DIR}/include"
    PRIVATE include
)
target_link_libraries(my_exe my_managed_dll my_dll_using_expat)

configure_file(include/version.in.h include/version.h ESCAPE_QUOTES @ONLY)

add_custom_command(
    TARGET my_exe POST_BUILD
    COMMAND "${CMAKE_COMMAND}" -E copy
        "$<TARGET_FILE_DIR:my_managed_dll>/my_managed_dll.dll.config"
        "$<TARGET_FILE_DIR:my_exe>/my_exe.exe.config"
)

# Had to add this to also copy expat DLL.
add_custom_command(
    TARGET my_exe POST_BUILD
    COMMAND "${CMAKE_COMMAND}" -E copy_if_different
        "$<TARGET_FILE_DIR:my_dll_using_expat>/expat.dll"
        "$<TARGET_FILE_DIR:my_exe>"
)

my_managed_dll /的CMakeLists.txt：

set(
    SOURCES
    ...
)

add_library(my_managed_dll SHARED ${SOURCES})

target_compile_options(my_managed_dll PRIVATE /clr /EHa)

# We need to remove this flag for CLR support to work.
string(REPLACE /RTC1 "" CMAKE_CXX_FLAGS_DEBUG "${CMAKE_CXX_FLAGS_DEBUG}")

target_compile_definitions(my_managed_dll PRIVATE _UNICODE)
target_include_directories(my_managed_dll PUBLIC include PRIVATE src)

add_custom_command(
    TARGET my_managed_dll POST_BUILD
    COMMAND "${CMAKE_COMMAND}" -E copy
        "${CMAKE_CURRENT_SOURCE_DIR}/src/my_managed_dll.config"
        "$<TARGET_FILE_DIR:my_exe>/my_exe.dll.config"
)

my_dll_using_expat /的CMakeLists.txt：

set(
    SOURCES
    ...
)

add_library(my_dll_using_expat SHARED ${SOURCES})

target_compile_definitions(my_dll_using_expat PRIVATE _UNICODE)
target_include_directories(
    my_dll_using_expat
    PUBLIC include
    PUBLIC ${EXPAT_INCLUDE_DIRS}
    PRIVATE src
)
target_link_libraries(my_dll_using_expat ${EXPAT_LIBRARIES})

add_custom_command(
    TARGET my_dll_using_expat POST_BUILD
    COMMAND "${CMAKE_COMMAND}" -E copy_if_different
        "${EXPAT_INCLUDE_DIR}/../bin/expat.dll"
        "$<TARGET_FILE_DIR:my_dll_using_expat>"
)

CMake不会自动复制DLL
