[CMake] generating source files with ADD_CUSTOM_COMMAND

[Hicham Mouline]

That must be it, obvious indeed,

 

Thank you,

Did you build yet?

 

Custom commands are executed at build time, not at cmake configure time.

I added the -E, no difference.

 

Shouldn't an error have been printed the first time round when I didn't have
the -E.  There was no error.

I traced it and the ADD_CUSTOM_COMMAND was in the trace.

Is this an indication that line is not executed at all?

I think you mean:

${CMAKE_COMMAND} -E copy src dst

 

You forgot the -E.
