通过CMake

Question

我正在尝试在CMakeLists文件中为我的项目添加post build事件。 这个构建后的事件必须将Qt库放在我的可执行文件附近。 我使用add_custom_command来执行此操作：

set(libraryFileName ${QtDir}/bin/${packageName}.dll)

# Copy qt library after build
add_custom_command(
    TARGET ${target} POST_BUILD             #Path to cmake executable file
    COMMAND "${CMAKE_COMMAND}" -E           #CMake in command mode
        copy                                #Copy command
        "${libraryFileName}"                #Path to the file
        "$<TARGET_FILE_DIR:${target}>"      #Where to copy
    COMMENT "Copying to output directory")

主要问题是如何为每个系统正确生成libraryFileName？我的意思是，我的灵魂适用于Windows，但我想其他系统类型都会失败。有没有办法获得共享库的扩展而不是硬编码？

我找到了解决方案。但它可能只适用于Qt。

# Get package location
get_target_property(location ${qtVersion}::${shortPackageName} LOCATION)

# Copy qt library after build
add_custom_command(
    TARGET ${target} POST_BUILD             #Path to cmake executable file
    COMMAND "${CMAKE_COMMAND}" -E           #CMake in command mode
        copy                                #Copy command
        "${location}"                       #Path to the file
        "$<TARGET_FILE_DIR:${target}>"      #Where to copy
    COMMENT "Copying ${packageName}...")

您可以添加平台检查器并根据该检查设置变量。

object CheckCommand "apt" {
  import "plugin-check-command"
  command = [ PluginDir + "/check_apt" ]
  timeout = 5m
  arguments += {
      "--critical" = {
          description = "If the full package information of any of the upgradable packages match this REGEXP, the plugin will return CRITICAL status. Can be specified multiple times."
          value = "$apt_critical$"
      }
      "--dist-upgrade" = {
          description = "Perform a dist-upgrade instead of normal upgrade. Like with -U OPTS can be provided to override the default options."
          value = "$apt_dist_upgrade$"
      }
      "--exclude" = {
          description = "Exclude packages matching REGEXP from the list of packages that would otherwise be included. Can be specified multiple times."
          value = "$apt_exclude$"
      }
      "--extra-opts" = {
          description = "Read options from an ini file."
          value = "$apt_extra_opts$"
      }
      "--include" = {
          description = "Include only packages matching REGEXP. Can be specified multiple times the values will be combined together."
          value = "$apt_include$"
      }
      "--timeout" = {
          description = "Seconds before plugin times out (default: 10)."
          value = "$apt_timeout$"
      }
      "--upgrade" = {
          description = "[Default] Perform an upgrade. If an optional OPTS argument is provided, apt-get will be run with these command line options instead of the default."
          value = "$apt_upgrade$"
      }
  }
