cmake：添加额外生成的文件

我有一个C文件，该文件已处理以生成两个.H文件。这些标题之一包含在C文件本身中，另一个C文件包括。

add_custom_command(OUTPUT header1.h header2.h
        COMMENT "Generating headers" 
        DEPENDS thecfile.c
        COMMAND ../mkheaders
        )

add_custom_target(generate_headers DEPENDS header1.h)
add_dependencies(rackmaster  generate_headers)

这有效，但是它总是会生成标头，而不是仅在“ thecfile.c”更改时。

如何修改它以创建适当的依赖性？

原文

I have a C file that is processed to generate two .h files. One of those headers is included in the c-file itself, another C file includes both.

add_custom_command(OUTPUT header1.h header2.h
        COMMENT "Generating headers" 
        DEPENDS thecfile.c
        COMMAND ../mkheaders
        )

add_custom_target(generate_headers DEPENDS header1.h)
add_dependencies(rackmaster  generate_headers)

This works, but it ALWAYS generates the headers, instead of only when "thecfile.c" changes.

How do I modify this to create the proper dependencies?
