Subject: [PATCH] - temporary solution to fix build of non-MSVC targets

Precompilation of prefix header for GCC and Clang requires some efforts thanks to CMake which doesn't support this feature out of the box
Existing thirparty solutions must be tuned to our needs, and our configuration should be adjusted to a chosen module
