Question

我正在尝试使用QT库编译一个简单的程序。问题是我无法弄清楚如何将这些库与CLion一起使用。这是我的CMakeLists.txt文件：

cmake_minimum_required(VERSION 3.3)
project(qt_1)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")

set(SOURCE_FILES main.cpp)

find_package( Qt5Core REQUIRED )
find_package( Qt5Widgets REQUIRED )
find_package( Qt5Gui REQUIRED )

add_executable(qt_1 ${SOURCE_FILES})

qt5_use_modules(qt_1 Core Widgets Gui)

我是从this post获取的。我也尝试了各种来源的多个例子，但我得到了同样的错误。

我编译时得到的错误是：

"C:\Program Files (x86)\JetBrains\CLion 1.2.4\bin\cmake\bin\cmake.exe" --build C:\Users\Andrei\.CLion12\system\cmake\generated\5ef88d9c\5ef88d9c\Debug --  target qt_1 -- -j 8

  asked CMake to find a package configuration file provided by "Qt5Core", but
  CMake did not find one.

  Could not find a package configuration file provided by "Qt5Core" with any
  of the following names:

    Qt5CoreConfig.cmake
    qt5core-config.cmake

  Add the installation prefix of "Qt5Core" to CMAKE_PREFIX_PATH or set
  "Qt5Core_DIR" to a directory containing one of the above files.  If
  "Qt5Core" provides a separate development package or SDK, be sure it has
  been installed.


mingw32-make.exe: *** [cmake_check_build_system] Error 1
Makefile:175: recipe for target 'cmake_check_build_system' failed

我正在运行windws 8.1，我已将QT bin文件夹添加到路径。

UPDATE1： CMakeLists.txt现在工作正常，我可以包括QT库没有问题。但是现在我在编译时得到了这个东西：

undefined reference to `_imp___ZN12QApplicationC1ERiPPci'

这是我当前的CMakeLists.txt文件：

cmake_minimum_required(VERSION 3.3)
project(qt_1)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
set(CMAKE_PREFIX_PATH C:/Qt/5.6/msvc2015_64)

set(SOURCE_FILES main.cpp)

find_package( Qt5Core REQUIRED )
find_package( Qt5Widgets REQUIRED )
find_package( Qt5Gui REQUIRED )

add_executable(qt_1 ${SOURCE_FILES})

qt5_use_modules(qt_1 Core Widgets Gui)

使用CLION和QT
