ubuntu 的 QtCore 安装

Question

我一直在尝试安装 torch，但在运行 ./install.sh 时出现以下错误

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

我已经尝试使用

安装 QtCore

sudo apt-get install libqt4-core

但是，我仍然收到一个错误:

Could NOT find QtCore

如上图。为什么会这样，我该如何解决？

安装步骤: http://torch.ch/docs/getting-started.html#_

编辑(已解决):我还必须使用

安装 qt4-dev-tools

apt-get install qt4-dev-tools

我通过将我所有 CMakeList.txt 中的 find_package(Qt4 REQUIRED) 替换为 find_package(Qt5Widgets) 解决了这个问题。
