应该如何安装 QtOpenGL 才能使 cmake 能够找到它？

我有这个问题尝试从源安装 Extcalc 时：

ezio@Cantabury ~/Downloads/extcalc-0.9.3-1 $ cmake .
-- Looking for Q_WS_X11
-- Looking for Q_WS_X11 - found
-- Looking for Q_WS_WIN
-- Looking for Q_WS_WIN - not found.
-- Looking for Q_WS_QWS
-- Looking for Q_WS_QWS - not found.
-- Looking for Q_WS_MAC
-- Looking for Q_WS_MAC - not found.
-- Found Qt-Version 4.8.7 (using /usr/bin/qmake)
Qt QTOPENGL library not found.
-- Configuring done

-- Build files have been written to: /home/ezio/Downloads/extcalc-0.9.3-1

解决方案是“重新构建 Qt，并特别注意启用 QtOpenGL 模块的构建”。问题是我通过 apt-get 安装了所有东西，包括 Qt，我想我还安装了 QtOpenGl。具体来说，在尝试让它工作的过程中，我安装了这些软件包（除了系统上已有的一些其他核心 Qt 模块）：

libqt4-opengl, python-qt4-gl, build-essential, qt4-dev-tools, libqt4-dev

以及 Mazze 建议的软件包列表：

apt-get install libfontconfig1-dev libfreetype6-dev libx11-dev libxext-dev libxfixes-dev libxi-dev libxrender-dev libxcb1-dev libx11-xcb-dev libxcb-glx0-dev libxcb-keysyms1-dev libxcb-image0-dev libxcb-shm0-dev libxcb-icccm4-dev libxcb-sync0-dev libxcb-xfixes0-dev libxcb-shape0-dev libxcb-randr0-dev libxcb-render-util0-dev

我在网上找不到任何其他有关安装 QtOpenGl（没有整个 Qt 包）的资源。

  • 我如何检查我是否确实安装了此模块？
  • 如果有的话，我怎样才能让 cmake 找到它？
  • 如果没有，最简单的安装方法是什么？

以下是我认为可能相关的 CMakeList.txt 部分。剪切部分由 [...] 表示。
