Revision history [back]

Hi,

I have followed this tutorial step by step, only changed ninja to nmake (I was not able to build the ninja). After the cmake finished, I run nmake in newly created directory and got this error (this is only a few lines):

Do you have any idea what is wrong?

Thanks for any help :).
