Missing definition of MBEDTLS_ECP_MAX_BITS

[Zw1d]

Hi,
I'm trying to rewrite one of the examples to a new project (so it's easier to read and understand) but I keep getting this error while compiling:

In file included from /home/x/newproject/lib/mbedtls/include/mbedtls/ecdh.h:38,
                 from /home/x/newproject/lib/mbedtls/3rdparty/everest/library/everest.c:26:
/home/x/newproject/lib/mbedtls/include/mbedtls/ecp.h:362:2: error: #error "Missing definition of MBEDTLS_ECP_MAX_BITS"
  362 | #error "Missing definition of MBEDTLS_ECP_MAX_BITS"
      |  ^~~~~
make[2]: *** [lib/mbedtls/3rdparty/everest/CMakeFiles/everest.dir/build.make:76: lib/mbedtls/3rdparty/everest/CMakeFiles/everest.dir/library/everest.c.obj] Error 1
make[1]: *** [CMakeFiles/Makefile2:2151: lib/mbedtls/3rdparty/everest/CMakeFiles/everest.dir/all] Error 2
make: *** [Makefile:136: all] Error 2

It's definitely my mistake, since the original examples compile successfully . So far I found out that for some reason the version of mbedtls that is being pulled to my project differs from the one that is being pulled to this repo's examples - it compiles fine if I just move the library from examples dir to my new project dir. I have tried manually setting mbedtls version to the same commit like in examples dir, but it doesn't help. So I'm thinking if maybe I can just "calm mbedtls down" with setting what it needs, but setting MBEDTLS_ECP_MAX_BITS in port/mbedtls/inc/ssl_config.h doesn't do anything...

I realize this description is messy, but I'm honestly out of ideas how to resolve this issue and where to start... And help would be appreciated.
