build of Irrlicht failing on x86_64 linux with relocate errors.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Find an x86_64 linux machine without libpng-dev, libjpeg-dev or libbz2-dev 
libraries installed
2. Run cmake followed by make
3. Observe errors reported in BuildingOpenNero comments

This problem is due to Irrlicht attempting to incorrectly link with libpng, 
libjpeg or libbz2 libraries built from included source.

The workaround for this problem is to install the packages:
  * libpng-dev
  * libjpeg-dev
  * libbz2-dev
Before proceeding with the cmake step.

However, it should be possible to change the build process so that linking 
works correctly in the absence of these libraries.

It may be good to note that this will pop up when running cmake without the 
libraries:

-- Could NOT find JPEG (missing:  JPEG_LIBRARY JPEG_INCLUDE_DIR) 
-- Could NOT find BZip2 (missing:  BZIP2_LIBRARIES BZIP2_INCLUDE_DIR) 

After installing the dev packages, these messages went away and make ran 
without a problem for me.  Thanks much.

It may be worth mentioning that you want libpng 1.2. Irrlicht does not compile 
against 1.5:
