[CMake] FW: cmake newbie questions

[Mike Jackson]

What is actually going on is that CMake is actually compiling and  
_running_ a small application to determine what endian type the  
machine is. I am guessing that the z/OS executable will not actually  
_run_ on your host system so it will give an error. If you know FOR  
SURE that z/OS will ALWAYS be big endian then you can probably  
manually set the variable yourself and be just fine.
