如何使用premake从C ++项目复制所有标头

Question

I have a C++ project with its source files (.cpp and .h files) in a directory called src and its subdirectories. I want, once my project is compiled, to copy all the header files from this source folder into another directory, maintaining the folderstructure of src.

I have tried to copy these files with post-build commands:

postbuildcommands
{
    "{COPY} src/*.h include"
}

and

postbuildcommands
{
    "{COPY} src/**.h include"
}

But these only copy the .h files directly in src and not those in subdirectories. For example, this

src
+-- a.h
+-- a.cpp
+-- sub
|   +-- b.h
|   +-- b.cpp

becomes

include
+-- a.h

instead of

include
+-- a.h
+-- sub
|   +-- b.h

Answer 1

Are you using windows linux or mac? Or does it need to be cross platform?

It looks like the {copy} token doesn't pass the /s flag to xcopy on windows https://github.com/premake/premake-core/wiki/Tokens https://docs.microsoft.com/en-us/windows-server/administration/windows-commands/xcopy

One possible solution is to find all files or get them from the project somehow and create a postbuild command for each header file which might be a lot slower
