Propagate "static" to external dependencies

[mardy]

Hi!
I have a project which builds a static library. This library is used as a dependency by other (shared) libraries, and also by a program that must be statically linked. The problem I'm facing is with external dependencies:

rpm_support = static_library(
    'rpm-support',                   
    [                
        'rpm.cpp',                        
    ],                                  
    dependencies: [                         
        dependency('rpm'),
    ]             
)                                                                    

The definition above works well when rpm_support is used by a shared library or by a non-static executable; but when used in the statically linked program, the external rpm dependency gets resolved as librpm.so, whereas I need it to be librpm.a. Is there a way to propagate the "static" flag of the user of the dependency to the external dependencies?

Something like:

rpm_support = static_library(
    'rpm-support',                   
    [                
        'rpm.cpp',                        
    ],                                  
    dependencies: [                         
        dependency('rpm', static: rpm_support.static),
    ]             
)
