Flutter windows：我可以使用相对路径在 CMakeLists.txt 中捆绑 `.dll` 库吗？

Question

我正在构建一个 flutter 插件，它从 lib.dll 文件调用本机函数，并且在我的计算机中一切正常。

但我使用 link 的相对路径 lib 例如

E:/_Projects/mahesabu/client/packages/server/windows/lib.dll

现在我想在 CI/CD 中移动构建过程，我相信使用相对路径，例如 ./lib.dll 会很容易。

当然我是 cmake 配置的新手。在一条评论中写着

List of absolute paths to libraries that should be bundled with the plugin

我想知道如何在那里使用相对路径，因为如果我尝试构建失败。以下为CMakeLists.txt

cmake_minimum_required(VERSION 3.14)
set(PROJECT_NAME "server")
project(${PROJECT_NAME} LANGUAGES CXX)

# This value is used when generating builds using this plugin, so it must
# not be changed
set(PLUGIN_NAME "server_plugin")

add_library(${PLUGIN_NAME} SHARED
  "server_plugin.cpp"
)
apply_standard_settings(${PLUGIN_NAME})
set_target_properties(${PLUGIN_NAME} PROPERTIES
  CXX_VISIBILITY_PRESET hidden)
target_compile_definitions(${PLUGIN_NAME} PRIVATE FLUTTER_PLUGIN_IMPL)
target_include_directories(${PLUGIN_NAME} INTERFACE
  "${CMAKE_CURRENT_SOURCE_DIR}/include")
target_link_libraries(${PLUGIN_NAME} PRIVATE flutter flutter_wrapper_plugin)

# List of absolute paths to libraries that should be bundled with the plugin
set(server_bundled_libraries
  ""
  "E:/_Projects/mahesabu/client/packages/server/windows/lib.dll" #USE RELATIVE PATH HERE
  PARENT_SCOPE
)

我们将不胜感激。

Answer 1

只需使用：

set(server_bundled_libraries "${CMAKE_CURRENT_SOURCE_DIR}/lib.dll" PARENT_SCOPE)

CMAKE_CURRENT_SOURCE_DIR 变量将扩展到 add_subdirectory 跟踪的当前源目录。这通常是当前 CMakeLists.txt 所在的目录，但并非总是如此。据推测，这是 E:/_Projects/mahesabu/client/packages/server/windows 在您的计算机上（根据您的评论，您希望 ./lib.dll 可以工作），但会在 CI 或其他地方。
