Question

所以我一直试图用QPrinter让我的程序用cmake + mingw + qt5.2进行编译但是我遇到了问题：以下测试程序无法编译，因为它找不到QPrinter应该是它的一部分QtCore

#include <QPrinter>
#include <QApplication>
#include <windows.h>

int main()
{
    QApplication a( argc, argv );

    return 0;
} // end

这是我的cmake文件

    SET(CMAKE_C_COMPILER E:/Qt/Qt5.2.1/Tools/mingw48_32/bin/gcc.exe)
    SET(CMAKE_CXX_COMPILER E:/Qt/Qt5.2.1/Tools/mingw48_32/bin/g++.exe)
    cmake_minimum_required(VERSION 2.8)

    PROJECT (test_prog)
    add_definitions(-std=c++11)
    SET( test_prog_SRCS test.cpp)
      # Tell CMake to run moc when necessary:
      set(CMAKE_AUTOMOC ON)
      # As moc files are generated in the binary dir, tell CMake
      # to always look for includes there:
      set(CMAKE_INCLUDE_CURRENT_DIR ON)

      # Widgets finds its own dependencies.
      find_package(Qt5Widgets REQUIRED)
      find_package(Qt5Core REQUIRED)
      find_package(Qt5Gui REQUIRED)

    include_directories(
        ${Qt5Widgets_INCLUDE_DIRS}
        ${Qt5Gui_INCLUDE_DIRS}
        ${Qt5Core_INCLUDE_DIRS}
    )

    add_executable(test_prog WIN32  ${test_prog_SRCS})
    target_link_libraries(test_prog ${Qt5Widgets_LIBRARIES} ${Qt5Core_LIBRARIES} ${Qt5Gui_LIBRARIES} )

错误是：

test.cpp：1：20：致命错误：QPrinter：没有这样的文件或目录
#include <QPrinter>

有没有人知道让这个工作的正确咒语？

使用CMake 2.8.11：

SET(CMAKE_C_COMPILER E:/Qt/Qt5.2.1/Tools/mingw48_32/bin/gcc.exe)
SET(CMAKE_CXX_COMPILER E:/Qt/Qt5.2.1/Tools/mingw48_32/bin/g++.exe)
cmake_minimum_required(VERSION 2.8.11)

PROJECT (test_prog)
add_definitions(-std=c++11)
SET( test_prog_SRCS test.cpp)
# Tell CMake to run moc when necessary:
set(CMAKE_AUTOMOC ON)
# As moc files are generated in the binary dir, tell CMake
# to always look for includes there:
set(CMAKE_INCLUDE_CURRENT_DIR ON)

find_package(Qt5PrintSupport REQUIRED)

add_executable(test_prog WIN32  ${test_prog_SRCS})
target_link_libraries(test_prog Qt5::PrintSupport)

无法让QPrinter使用cmake进行链接
