Can't build 1.4.1555 due to dependency from libusrsctp

[ghost]

I'm building psi like this on Linux:

mkdir build
cd build
CFLAGS="$SLKCFLAGS" \
cmake \
    -DCMAKE_C_FLAGS="$SLKCFLAGS" \
    -DCMAKE_CXX_FLAGS="$SLKCFLAGS" \
    -DCMAKE_BUILD_TYPE="Release" \
    -DCMAKE_INSTALL_PREFIX=/usr \
    -DUSE_ENCHANT=ON \
    -DUSE_HUNSPELL=OFF \
    -DBUNDLED_USRSCTP=OFF \
    -DUSE_KEYCHAIN=ON \
    -DINSTALL_PLUGINS_SDK=ON \
    -DBUNDLED_QCA=ON \
    -DENABLE_PLUGINS=ON \
    .. .


QMAKE_CFLAGS="$SLKCFLAGS" \
QMAKE_CXXFLAGS="$SLKCFLAGS" \
make
make install INSTALL_ROOT=$PKG

The code won't build and prints:
