Linking error against spirv-tools

[meerfrau]

I've built successfully against git master of https://github.com/KhronosGroup/SPIRV-Tools. shaderc was compiled via

  cmake \
    -B build \
    -DCMAKE_BUILD_TYPE=Release \
    -DCMAKE_INSTALL_PREFIX=/usr \
    -DCMAKE_CXX_FLAGS="$CXXFLAGS -ffat-lto-objects" \
    -DSHADERC_SKIP_TESTS=ON \
    -Dglslang_SOURCE_DIR=/usr/include/glslang \
    -GNinja
  ninja -C build

But whenever I try to link against shaderc in my programs there is a linking error. Using mold or lld made no difference:
