QtCore installation for ubuntu

Question

我一直在尝试安装torch，但在运行时遇到以下错误/安装.sh

CMake Error at /usr/share/cmake-2.8/Modules/FindQt4.cmake:664 (message):
  Could NOT find QtCore.  Check
  /home/name/torch/exe/qtlua/build/CMakeFiles/CMakeError.log for more
  details.
Call Stack (most recent call first):
  CMakeLists.txt:38 (FIND_PACKAGE)

-- Configuring incomplete, errors occurred!
See also "/home/name/torch/exe/qtlua/build/CMakeFiles/CMakeOutput.log".
Error: Build error: Failed building.
Missing dependencies for qttorch:
qtlua >= 1.0

我已经尝试过使用安装QtCore

sudo apt-get install libqt4-core

但是，我还是得到了一个错误：

Could NOT find QtCore

如上所示。为什么会这样？我该如何解决？

安装时我遵循的步骤：http://torch.ch/docs/getting-started.html#_

编辑（已解决）：我不得不使用安装qt4开发工具

apt-get install qt4-dev-tools

Answer 1

我通过在所有CMakeList.txt中将find_package（Qt4 REQUIRED）替换为find_packages（Qt5Widgets）来解决这个问题。

用CMake 检测Qt5
