安装 Audiveris OCR 进行音乐符号处理

我正在尝试安装 Audiveris OCR 来制作音乐符号。作为安装的一部分，我已按照以下说明安装了 Microsoft VC++ 环境。

我的问题是关于说明的第二部分：“系统环境变量 TESSDATA_PREFIX 设置为 /ocr/（包括最后的“/”字符），以便 Tesseract 软件可以检索自己的数据“”。

我应在哪里以及如何执行此操作？

谢谢。

这是从 Audiveris 网站获取的：

*   Microsoft VC++ 2008 to be installed beforehand (the free express edition is fine).
* The system environment variable TESSDATA_PREFIX to be set to <install-dir>/ocr/ (including the final "/" character) so that Tesseract software can retrieve its own data.
