Add cmake build files for ToneGenerator

[Paxa]

I used this instruction http://lpapp.blogspot.com/2013/02/geekish-application-development-for.html

Still have some issue: Application doesn't run if compile with flag -DUSING_GL20, only with -DUSING_GL11

Btw do you know how to find out correct lib file for function? (from lib/ folder). It's not always have same name with .h file

Hi.

The main GL code in this sample app (which I wrote) is written in GL ES 1.1, which is why you cannot build it using GL ES 2. The bbutil modules were taken from other published samples and were updated to be used in both GL ES 1.1 and GL ES 2 projects. I am working on new sample apps where I am using GL ES 2 and once they are complete, I may circle back and update some of my older samples to also work with GL ES 2. If you would like to see this sample app updated to work with GL ES 2, let me know and I can convert it first but I probably won't get a chance to do that for another two weeks at least.

Thank you. What do you think about cmake ?
