[CMake] Fwd: cmake_policy(VERSION 2.4) = no exe's generated

[Frank Bonniwell]

Hello Eric,


Thank you so much for the tip. I was able to successfully compile.
The cmake_minimum_required(VERSION 2.6.0) is what fixed it!

Also thank you for the "make VERBOSE =1" tip.
This was also very helpful.


If you are beginning to use CMake why do you have such an older policy
as of CMake 2.4?

The code was originally developed with CMake 2.4. It just required some
library and CMakeList.txt updates.


Cheers,

Frank
