Providing path to package dependency from CLI, and falling back to xmake's searcher. How to do it?

[corpserot]

in xmake.lua:

set_project('my-project')
set_version('0.1')

-- how do i override this and provide my own include+library paths from CLI?
add_requires('my-dependlib')

target('my-lib')
    add_files('main.c')
    add_package('my-dependlib')

in shell:

# don't want to use xmake's package searcher. give my own paths for this special build.
xmake f --my-dependlib-includes=path/to/include --my-dependlib-lib=path/to/lib

# but this must also work, whether from system or from fetching+building
xmake f

my solution looked something like this. if there is a cleaner approach, i'd appreciate if someone shares it ❤️

set_project('my-project')
set_version('0.1')

option('mydependlib-libpath')
    set_description('Path to mydependlib library')
option_end()

option('mydependlib-includepath')
    set_description('Path to mydependlib headers')
option_end()

if not has_config('mydependlib-libpath', 'mydependlib-includepath') then
    add_requires('mydependlib')
end

target('my-lib')
    add_files('main.c')
    add_links('mydependlib')
    
if has_config('mydependlib-libpath', 'mydependlib-includepath') then
    add_includedirs('$(mydependlib-includepath)')
    add_linkdirs('$(mydependlib-libpath)')
else
    add_package('mydependlib')
end
