Installing with `pecl` command-line utility
1. Install OpenCV libraries (at least version 1.0.0)
2. Execute command "pecl install facedetect"
3. Make sure you have extension=facedetect.so in your php.ini
Installing from sources
1. Install OpenCV libraries (at least version 1.0.0)
2. Unpack facedetect source package
3. Go to facedetect folder and type "phpize && ./configure && make && make install"
4. Make sure you have extension=facedetect.so in your php.ini
Compiling Facedetect into PHP
1. Install OpenCV libraries (at least version 1.0.0)
2. Unpack facedetect source package to $PHP_SOURCE_DIR/ext/facedetect
3. In php source root directory run commands: "rm configure && ./buildconf --force"
4. Configure PHP with command "./configure --with-facedetect"
5. Run make && make install
