Qt5 cmake引用private头文件

Qt5 cmake引用private头文件

如何引用Qt的qzipreader_p.h头文件 、xlsxzipreader_p.h头文件

使用 target_include_directories

target_include_directories(TestQtXlsx PRIVATE
                           ${Qt${QT_VERSION_MAJOR}Gui_PRIVATE_INCLUDE_DIRS}
                           ${Qt${QT_VERSION_MAJOR}Xlsx_PRIVATE_INCLUDE_DIRS}
                        )

注:Qt Xlsx是第三方库，安装请参照Qt Xlsx安装教程

完整的例子

CMakeLists.txt

cmake_minimum_required(VERSION 3.14)

project(TestQtXlsx LANGUAGES CXX)

set(CMAKE_INCLUDE_CURRENT_DIR ON)

set(CMAKE_AUTOUIC ON)
set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTORCC ON)

set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

find_package(QT NAMES Qt6 Qt5 COMPONENTS Core Gui Xlsx REQUIRED)
find_package(Qt${QT_VERSION_MAJOR} COMPONENTS Core Gui Xlsx  REQUIRED)


add_executable(TestQtXlsx
  main.cpp
)

target_include_directories(TestQtXlsx PRIVATE
                           ${Qt${QT_VERSION_MAJOR}Gui_PRIVATE_INCLUDE_DIRS}
                           ${Qt${QT_VERSION_MAJOR}Xlsx_PRIVATE_INCLUDE_DIRS}
                        )

target_link_libraries(TestQtXlsx Qt${QT_VERSION_MAJOR}::Core)
target_link_libraries(TestQtXlsx Qt${QT_VERSION_MAJOR}::Xlsx)
target_link_libraries(TestQtXlsx Qt${QT_VERSION_MAJOR}::Gui)
