Each source compilation generates a dependencies file. These dependencies files are consolidated in one file per target. This consolidation is done as part of command 'cmake -E cmake_depends` launched before evaluation of makefile dependency graph. The consolidation uses the same approach as `CMake` dependencies management. Fixes: #21321
