WP: multiple meta_query from array

I wasted some hours on that…. to know how can i get multiple meta_query like :

'meta_query' => array(
    'relation' => 'OR',
    array(
        'key' => 'mykey',
        'value' => 'value1',
        'compare' => '='
    ),
    array(
        'key' => 'mykey',
        'value' => 'value2',
        'compare' => '='
    ),
)

from a simple array like :

$mykey = array( 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 );

I need to generate the meta_query automatically because the array is not always the same. Thank you by advance! Julian
