[CMake] Setting the C dialect

[Mattias Holm]

Hi there,

I am new to the list, so excuse me if this has been asked before.

I am trying to figure out if there is a good way of setting the  
language dialect that you are using. For example, I am working with a  
project written in C99, and thus I need to specify this.

Sure enough, I can use SET_SOURCE_FILES_PROPERTIES and set the  
compile flags for every C-file to -std=c99/gnu99 and at least that  
will work with GCC. Is there any way to do this portably, and without  
setting the compile flags on every source file?

I am hoping of having support for Windows without the need for gcc  
and Cygwin.


Best regards,
Mattias
