안녕하세요!

Taejong, did you install libwebsockets from their repo or it's the system one? If you use the system libs you want to install the libs from official repo. Try to follow these steps and then try to compile janus again:

git clone https://libwebsockets.org/repo/libwebsockets
cd libwebsockets
git checkout v3.2.0
mkdir build
cd build
cmake -DLWS_MAX_SMP=1 -DCMAKE_INSTALL_PREFIX:PATH=/usr -DCMAKE_C_FLAGS="-fpic" ..
make && sudo make install

Hope it helps you.
