Replace STREQUAL cases with variable checks

As I was investigating the NO_UNITY_BUILD_SOURCES issue, I realized that
we don't need to pass these quoted, especially now that we have moved
to `cmake_parse_arguments(PARSE_ARGV`, and we can check their existence
just by checking the `arg_*`, and that should be sufficient.

I also left a warning that we are aware of this.
