Dependencies install with -i option works OK.

Additional dependencies with -t option:
- rocksdb - OK
- librxe - OK
- iscsi - OK
- ocf - OK
- flamegraph - OK
- tsocks - OK
- nvmecli - OK
- fio - compilation errors on version 3.3
	OK if updated to 3.15
- qemu - OK, but need to disable some error warnings:
	-Wno-error=stringop-truncation
	-Wno-error=deprecated-declarations
	-Wno-error=incompatible-pointer-types
	-Wno-error=format-truncation
- qat - not run
