Good day. I am getting hung up compiling the CAmkES compiles. I'm getting following error which I believe is because the version.h.d does not exist. Where is the version set? 

thx

ive traced it down I think to this block in the Cmakeadd_custom_command(

    OUTPUT ${CMAKE_CURRENT_BINARY_DIR}/include/version.h
