c++ - Meson 将头文件复制/安装到输出目录并保留文件夹结构

Question

基本上我希望能够混合使用 install_subdir 和 install_headers 函数。
我想将所有头文件从项目源目录复制到其他目录，并仍然保留子目录结构。

来源

MyProject  
|-- folder1  
|   |-- file11.h  
|   |-- file11.cpp  
|   |-- file12.h  
|   `-- file12.cpp  
`-- folder2  
    `-- file21.h

目的地

MyProject
|-- folder1
|   |-- file11.h
|   |-- file12.h
`-- folder2
    `-- file21.h

我尝试的是复制源目录并排除所有 cpp 文件，然后仅使用预期的 install_headers() 函数，但两者均无效。
我对我所做的事情以及原因添加了评论。也许有人知道发生了什么事:

project('MyProject', 'cpp')

test_src = [  'src/MyProject/folder1/file11.cpp'
              'src/MyProject/folder1/file12.cpp']

# Passing files seems to be preferred but exclude_files only takes list of strings
# test_src = files([  'src/MyProject/folder1/file11.cpp'
#                     'src/MyProject/folder1/file12.cpp'])

test_hdr = files([  'src/MyProject/folder1/file11.h',
                    'src/MyProject/folder1/file12.h',
                    'src/MyProject/folder2/file21.h'])


base_dir = meson.current_source_dir()

static_library('MyProject', name_prefix: '', name_suffix : 'lib', 
                sources: test_src,
                install: true,
                install_dir: base_dir + '/build/lib')

# Produces flat hierarchy       
install_headers(test_hdr, install_dir: base_dir + '/build/include')

# Also copies all cpp files into destination folder
install_subdir('src/MyProject', install_dir: base_dir + '/build/include', exclude_files: '*.cpp')

# Same result as wildcard exclusion
install_subdir('src/MyProject', install_dir: base_dir + '/build/include', exclude_files: test_src)

有人能解决这个问题吗？
如果任何方法需要的话，我有我的来源和标题的完整列表。
我目前正在通过 shell 命令复制文件，但最好将其包含到安装/构建过程中。

我在 Windows 上使用介子构建。

我找到了一个可以满足我要求的解决方法。
如果有人找到更好的解决方案，需要所有头文件的列表，请随时回答，我会接受它。

现在这就是我所做的:

project('MyProject', 'cpp')


test_src = files([  'src/MyProject/folder1/file11.cpp',
                    'src/MyProject/folder1/file12.cpp' ])

# Note that i'm omitting the base folder here since exclude_files searches relative to the subdir path
# Also, forward slash doesnt work. You have to use double backslash
test_src_exclude = [  'folder1\\file11.cpp',
                      'folder1\\file12.cpp' ]

dir_base = meson.current_source_dir()
dir_install = join_paths(dir_base, 'build/meson-out/MyProject')
dir_install_hdr = join_paths(dir_install, 'include')

static_library('MyProject', name_prefix: '', name_suffix : 'lib', 
                sources: test_src,
                install: true,
                install_dir: dir_install)

install_subdir( 'src/MyProject', 
                install_dir: dir_install_hdr, 
                strip_directory: true,
                exclude_files: text_src_exclude)
