Unable to build Go app with cse tag

[Kevin_Rathgeber]

I have followed the steps here to install libmongocrypt and added the cse tag to my go build.

brew info libmongocrypt
==> mongodb/brew/libmongocrypt: stable 1.8.2, HEAD
C library for Client Side Encryption
https://github.com/mongodb/libmongocrypt

	Install HEAD version

Build results:

go build -ldflags "-X 'main.version=f0205c2409aa47ce7ac836784f364468af074380'" -tags cse -o /path/to/go/project/bin/apiserver cmd/apiserver/apiserver.go

This was working for me before but I believe i installed libmongocrypt before the release on Sept 5. I was helping a team member get set up so I uninstalled to walk through the installation with them and now it’s failing for both of us.

Our go-mongodriver version is v1.11.7

Any suggestions?

Also here is the pkg-config debug for libmongocrypt:

> pkg-config --debug --cflags --libs libmongocrypt

Error printing enabled by default due to use of output options besides --exists, --atleast/exact/max-version or --list-all. Value of --silence-errors: 0

This was resolved by running go clean -cache as described in this Github issue
