Use system dependencies (#11419)

* Try to improve gflags

* Try to improve gflags: part 2

* Tried to use dependencies on system

* Use nlohmann_jsonConfig from system

* Enabled nlohmann_json from system

* Improvements

* handle system gflags in developer package

* Simplifications

* Simplify dependency management

* Corrected package names

* Fixed subgraphsDumper configure stage

* Try to fix rhel8

* Try to fix macosx

* Fixed VPUX build

* Fixed aliasing issues

* Suppress some wanrings

* export gflags when build it

* Fixed some LTO

* Try to fix Mac

* revert

* use gflags as private dependency

* Aligned targets in developer package

* Fixed frontends tests build on U20 with LTO

* PAssed

* Don't use pkg_search_module(zlib ..) during cross-compilation

* Removed unused variables

* Fixed finding of zlib during cross-compilation
