fix: Using foreach to iterate through CFLAGS_OTHER

PkgConfig use 'separate_arguments' for pkgconfig result, so output
converted to the list (in cmake it's semicolumnt separated values).
If we try to append CFLAGS_OTHER as is, it will provide error for
more then one cflag in '.pc' file

Fix #4175, fix #4457.
