Want to know how to make multiple directory dependencies

Question details

Regarding the makefile below, I don't know why the following error occurs.
If it's one directory, it's successful, but if there are two, what should I do?
I just need to write two variables in the same dependent location and write the command normally, but it doesn't work.

What did you know

I want to know how to get the following console screen errors

Tried

There are two directories of files that depend on reference sites, so $< is $^ to specify all dependent files

I think the rule description is wrong.
Specifically, I think it would be good to describe the following in two rules.

Before:

$(OBJ_DIR)/%.o:src/%.cpp src/component/%.cpp
    $(CXX)-c-MMD-MP$^-o$@-I~/Library-I~/Library/freetype

After:

$(OBJ_DIR)/%.o:src/%.cpp
    $(CXX)-c-MMD-MP$^-o$@-I~/Library-I~/Library/freetype

$(OBJ_DIR)/%.o: src/component/%.cpp
    $(CXX)-c-MMD-MP$^-o$@-I~/Library-I~/Library/freetype

For obj/BoxCollider2D.o, the rule before the change seems to be interpreted as follows:

obj/BoxCollider2D.o:src/BoxCollider2D.cpp src/component/BoxCollider2D.cpp
 　 　$(CXX)-c-MMD-MP$^-o$@-I~/Library-I~/Library/freetype

(I can't read the source file in which directory from the question, so I'll write it down as being in src)
src/BoxCollider2D.cpp exists, so there is no src/component/BoxCollider2D.cpp, so make attempts to generate this file.
However, since there is no generation rule for src/component/BoxCollider 2D.cpp, the original rule does not apply as a result.

# If you run make-d to see how it works, the output will be
If it doesn't work the way you want it to, you should take a look at it.
