Linker problem

[andrew-palamar]

Hello, checked demo binaries from releases. Looks great, thanks for your work!
But when I try to build this project on Debian Bookworm or Trixie I have following errors:

FAILED: bin/c_cli/c_cli

ninja: build stopped: subcommand failed.

Used HEAD from main and latest tagged release. Both has same errors.

One thing I should mention. On Debian Trixie gcc version is gcc (Debian 14.2.0-8) 14.2.0. To build with it I had to add include:

diff --git a/src/phone/include/phone_instance_t.h b/src/phone/include/phone_instance_t.h
index 2ebfdbb..1d34bfc 100644

 class Endpoint;

No other edit to the source tree done.
Tried to use pjproject mentioned in README.md and from submodule with the same results.

Could you tell if those symbols belongs to libuuid or to pjproject itself?

sudo ldconfig -p | grep libuuid

libuuid.so.1 (libc6,x86-64) => /lib/x86_64-linux-gnu/libuuid.so.1
libuuid.so (libc6,x86-64) => /lib/x86_64-linux-gnu/libuuid.so

UPD:
After adding libuuid to phone libs it seems to link properly now. cpp_cli seems to run now. Have to check it with SIP server now.
