I'm working on a game project, which has multiple dependencies, including
curl and openssl. My goal is to have it working on its own, without any
system level dependencies, asside from those which do not make sense to have
at project level (such as X11, glibc, etc.). I was able to use LD_FLAGS and
CFLAGS set the appropriate directories to the openssl build and source
directories respectively
You probably meant LDFLAGS, no LD_FLAGS.
however it does not seem to have any effect, as the version I have available
is 3.0, but curl is linking against 1.1.0
You need to be aware that what you specify at link-time, isn't necessary the
same that's used later at run-time.
If you link your program to use libcurl as a shared library, it gets loaded at
run-time by ld.so and it typically has its own path to search in order to find
the libs. That doesn't have to then find the same lib!
On linux, you set the path in /etc/ld.so.conf, but you can also link your
program to use a specific set path or even change the path in your shell with
LD_LIBRARY_PATH.
None of this is curl specific.
