我正在尝试建立奥克拉尔来自源代码。我签出了提交8ab768从2012 年 7 月 10 日星期二 17:45:23 +0100。 然而，自由类型似乎缺少某些路径变量。以下是构建。

CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
FREETYPE_INCLUDE_DIR (ADVANCED)
used as include directory in directory /home/john/src/okular/generators/dvi
-- Configuring incomplete, errors occurred!
我已经尝试按如下方式设置环境变量。
$ export FREETYPE_INCLUDE_DIR=/usr/include/freetype2/freetype
但是好像没什么效果，我用的是Ubuntu 12.04。
Okular 的存储库可通过 Git 在 下获取git://anongit.kde.org/okular。

尝试使用-Dcmake的开关：
cmake .. -DFREETYPE_INCLUDE_DIR=/usr/include/freetype2/freetype ..。
