Build error on Alpine Linux

[SimpleWebTest]

Hello. I have problem with build app on Alpine Linux 3.8 (virt on XEN vm).
If cmake runed without options result is same.
Env: g++-6.4.0, gcc-6.4.0, lua5.1-dev, linux-headers-4.14.89, openssl-dev-1.0.2q, make-4.2.1, musl-dev-1.1.19, pcre-dev-8.42, binutils-2.30.
Can I build accel-ppp on Alpine Linux? What error with triton/libtriton.so?
Thank you for help!

CMake Deprecation Warning at CMakeLists.txt:3 (cmake_policy):
The OLD behavior for policy CMP0003 will be removed from a future version
of CMake.

The cmake-policies(7) manual explains that the OLD behaviors of all
policies are deprecated and that a policy should be set to OLD only under
specific short-term circumstances. Projects should be ported to the NEW
behavior and not rely on setting a policy to OLD.

ucontext.h not implemented in musl libc. so need update accell-ppp code to not use setcontext

You can try to run binary build with https://github.com/sgerrand/alpine-pkg-glibc/
