Perhaps, there is a way based on C++ standard to achieve what you wanted.
Generally, you cannot control an execution order of static constructors
in whole multi-module program, but the sequence of initialization of
static variables inside one module is predefined (in declaration order).
Additionally, in C++ you can use expressions in initializers and even
function calls. This leads to the following solution (if I got your
problem right):

extern  int  function_to_initialize_some_library( );
// this function does required 1st step of initialization

int  dummy_variable = function_to_initialize_some_library( );
// we declare dummy static variable to call initializing function
// in advance to the following declarations

// now we can invoke constructors: 2nd step of initialization
Class1	object1;
Class2	object2(arg);
// etc....
