The answer is:

    conf.sda_io_num = 13;
    conf.scl_io_num = 4;

Here is am small test program that worked with M5Stack-hardware. With M5cam-hardware it didn't work.

#include 
#include 
Adafruit_BMP085 bmp;

void setup() {
  Serial.begin(115200);
  //Wire.begin();       //Default
  Wire.begin(25,23);  //M5cam SDA, SCL
  //Wire.begin(21,22);  //M5Stack SDA, SCL

  Serial.println("\nStart program");
  if (!bmp.begin()) {
     Serial.println("Could not find a valid BMP085 sensor, check wiring!");
	  while (1) {
             Serial.println("Could not find a BMP085 sensor!");
	     delay(2000);
	  }
   }
}
  
void loop() {
    Serial.print("Temperature = ");
    Serial.print(bmp.readTemperature());
    Serial.println(" *C");    
   //...
    delay(500);
}
