I haven't tried that, but I think the only dependency the install target has 
is a dependency to "all", AFAIK it doesn't by itself drive the creation of 
file via add_custom_command().

To have a custom_command executed which produces a file which is not used in 
any target but which should be installed, you may have to use 
add_custom_command(... ALL ...) or something like that.
