Not sure why you got these errors, different machines have different environments, it is hard to find the reason.

Typically, we build milvus source by the following steps:

1. make sure the os meets the requirement
   Ubuntu 18.04 or later
   MacOS 12.0 or later

2. make sure the go/cmake/gcc version meet the requirement

go: >= 1.18
cmake: >= 3.18
gcc: 7.5

3. install the dependencies
   ./scripts/install_deps.sh

4. make

hit similar issue

To solve the issue, you will need to setup your PKG_CONFIG_PATH and some other system configs.

  export PKG_CONFIG_PATH="${PKG_CONFIG_PATH}:$ROOT_DIR/internal/core/output/lib/pkgconfig"
  export DYLD_LIBRARY_PATH=$ROOT_DIR/internal/core/output/lib
  export RPATH=$DYLD_LIBRARY_PATH;;

I set this on my goland configuration and it works

run setenv.sh should work as well
