I've edited my CMake script to link libcurl with my C application on Linux.

Besides adding libcurl to my target link libraries, I've set the libcurl flag DCURL_STATICLIB.

What is the definitive way of checking this has linked statically, rather than dynamically?

Run the ldd program on the generated executable(s). This will give you a list of all the shared libraries that are dynamically linked to it. Verify that libcurl.so is not on the list.

ldd my_executable

It may be useful to engage grep to filter out other shared libs:

ldd my_executable | grep libcurl

, but because that will produce no output when libcurl indeed is not dynamically linked to the executable. Nevertheless, the unfiltered form is useful at least for confirming that ldd actually worked.

Move all libcurl.so to another location with find and rename it.
