尝试从源代码构建Okular时出现“FreeType NOTFOUND”错误
我正在尝试从源代码构建Okular 。 我从Tue Jul 10 17:45:23 2012 +0100检查了提交8ab768 。 但是，某些路径变量中似乎缺少FreeType 。 这是cmake的输出。

$ export FREETYPE_INCLUDE_DIR=/usr/include/freetype2/freetype
但是，似乎没有效果。 我使用的是Ubuntu 12.04。
Okular的存储库可以通过git在git://anongit.kde.org/okular下git://anongit.kde.org/okular 。
尝试使用cmake的-D开关：
cmake .. -DFREETYPE_INCLUDE_DIR=/usr/include/freetype2/freetype ..
