如何自动复制xrc文件目录？

1、cmakelist文件中，设置target_compile_definitions，这样运行时，就会只调用项目src目录中的xrc文件。同时，作为冗余，添加复制命令。

target_compile_definitions(text2video_xrc PRIVATE
        UI_DIR="${CMAKE_SOURCE_DIR}/src/ui/"
        )
add_custom_command(TARGET text2video_xrc POST_BUILD
        COMMAND ${CMAKE_COMMAND} -E copy_directory
        ${UI_SOURCE_DIR}
        ${UI_TARGET_DIR}
        )

Cmakelist文件备份

cmake_minimum_required(VERSION 3.20)
project(text2video_xrc LANGUAGES CXX)

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/bin)
set(CMAKE_WIN32_EXECUTABLE ON)

# wxWidgets 路径
set(wxWidgets_ROOT_DIR "E:/cpp/wxWidgets-3.3.1/install")
set(wxWidgets_LIB_DIR "${wxWidgets_ROOT_DIR}/lib/gcc_x64_lib")

find_package(wxWidgets CONFIG REQUIRED COMPONENTS
        core
        base
        xrc
        aui
        html
        stc
        propgrid
        richtext
        )
include_directories(${wxWidgets_ROOT_DIR}/lib/gcc_x64_lib/mswu)


# 可执行文件
add_executable(text2video_xrc
        src/main.cpp

        )
include_directories(src)


add_compile_options(-finput-charset=UTF-8 -fexec-charset=UTF-8)

target_link_libraries(text2video_xrc PRIVATE wx::core wx::base wx::xrc wx::aui)
target_compile_definitions(text2video_xrc PRIVATE
        UI_DIR="${CMAKE_SOURCE_DIR}/src/ui/"
        )

if (WIN32)
    target_sources(${PROJECT_NAME} PRIVATE "${wxWidgets_DIR}/../../../include/wx/msw/wx.rc")
endif ()


set(UI_SOURCE_DIR "${CMAKE_SOURCE_DIR}/src/ui")
set(UI_TARGET_DIR "${CMAKE_RUNTIME_OUTPUT_DIRECTORY}/ui")

add_custom_command(TARGET text2video_xrc POST_BUILD
        COMMAND ${CMAKE_COMMAND} -E copy_directory
        ${UI_SOURCE_DIR}
        ${UI_TARGET_DIR}
        )
