LinuxQuestions.org - fontconfig was not found, but it is installed.

How can I adjust the path?
I want to compile vdr 2.2
http://tvdr.de/download.htm

Code:

scott@scott-MS-7596:~/Downloads/vdr-2.2.0$ make

Package fontconfig was not found in the pkg-config search path.

Perhaps you should add the directory containing `fontconfig.pc'

to the PKG_CONFIG_PATH environment variable

No package 'fontconfig' found

font.c:19:10: error: #include expects "FILENAME" or <FILENAME>
