What is the CMake equivalent of the GCC -c option?

For example, if I had a makefile that contains this:

dynArray.o: dynArray.c dynArray.h type.h 
    gcc -Wall -ansi -c dynArray.c

How would I translate that into a CMakeLists.txt file?

Since an object file alone is not the end result of what you are building, I suspect there is more context to the question that is missing. You are probably building an executable from the objects. Just use add_executable to specify your target and the source files that make up the target. Then use target_compile_definitions to specify the compile options you want while compiling source files for that target. For example:

add_executable(dynArray dynArray.c dynArray.h type.h)
target_compile_definitions(dynArray PRIVATE -Wall -ansi)

You can verify that the resulting compile commands are what you expect by using the Unix Makefiles generator and passing VERBOSE=1 to the make command:

mkdir build; cd build
cmake -G "Unix Makefiles" ..
make VERBOSE=1

This will cause the generated Makefile to display the full command lines used on every step of the build.

Probably CMake's object libraries would do that, that mean compile objects but not archive them like normal library would.

add_library(<name> OBJECT <src>...)
