Problem Installing mpdproxy

Usung linux mint 19.3 with gcc.
I'm trying to cinstall mpdproxy from github, but no instructions and
reading the makefile is beyond my grasp.

Project link below:

https://github.com/floriandejonckheere/mpdproxy

After downloading and trying 'make'
I get this error:

Code:make
gcc -fPIC -Wall -Werror -Wconversion -O3 -g -c -o mpdproxy.o mpdproxy.c
mpdproxy.c: In function th_sock_client':
mpdproxy.c:351:2: error: initialization from incompatible pointer type [-Werror=incompatible-pointer-types]
pthread_cleanup_push(&th_cleanup_client, connection);
^~~~~~~~~~~~~~~~~~~~
mpdproxy.c: In function th_sock_server':
mpdproxy.c:376:2: error: initialization from incompatible pointer type [-Werror=incompatible-pointer-types]
pthread_cleanup_push(&th_cleanup_server, connection);
^~~~~~~~~~~~~~~~~~~~
cc1: all warnings being treated as errors
<builtin>: recipe for target 'mpdproxy.o' failed
make: *** [mpdproxy.o] Error 1
Project is 5 years old so thanks in advance if anyone can help
or suggest alternate solutions.
