Error: cannot locate fontforge.h?报错

@王璐 你好，想跟你请教个问题：

报错如下：

[root@localhost coolwanglu-pdf2htmlEX-a124926]# cmake .
-- checking for module 'libfontforge>=2.0.0'
--   package 'libfontforge>=2.0.0' not found
Trying to locate old versions of fontforge...
CMake Error at CMakeLists.txt:62 (message):
  Error: cannot locate fontforge.h

-- Configuring incomplete, errors occurred!

centos 6.4    64位系统安装的包如下：

[root@localhost pdf2html]# ls
coolwanglu-pdf2htmlEX-a124926                    poppler-0.20.3.tar.gz
coolwanglu-pdf2htmlEX-v0.8.1-72-ga124926.tar.gz  
fontforge-20120731-b                            
fontforge_full-20120731-b.tar.bz2                xpdfbin-linux-3.03
poppler-0.20.3                                   xpdfbin-linux-3.03.tar.gz

fontforge-20120731-b  我用源码安装到了/usr/local/fontforge下

谢谢
