[CMake] inconsistent line endings in Visual Studio 2010

[Dominik Szczerba]

I am sorry to dig out this issue, but think the problem may still be with CMake.

I have made sure it is NOT printf and "\n" that generates this error.
The problem reported by MSVC is not UNIX endings, it is INCONSISTENT
endings. I made sure by replacing printf by fprintf and writing to my
config file directly from my test_run app rather then writing the
intercepted output to file. It is the interception that generates the
problem in MSVC. Specifically, intercepting the output results in
additional while characters, taken for Mac endlines by MSVC. You see
it by simply displaying the RUN_OUTPUT_VARIABLE variable: there are
additional empty lines between the intended (\n) lines. What and why
are these?

I found my way around it, just though it might still be worth investigating.

Regards,
Dominik
