in external/openssl/ExternalPackage_openssl.mk

 $(eval $(call gb_ExternalPackage_add_file,openssl,out32dll/ssleay32-lo.dll,out32dll/ssleay32.dll))
--> copy in instdir/out32dll

$(eval $(call gb_ExternalPackage_add_file,openssl,$(call gb_UnpackedTarball_get_dir,openssl)/out32dll/ssleay32-lo.dll,out32dll/ssleay32.dll))
 --> displays make: ***. and nothing copied
