cmake got "Could not found Go" error

here's the log:

I'v found the solution in https://github.com/devsisters/libquic/issues/8, sorry for creating this issue

I've met the same error. The solution works. But I'd like to know why we should have a Golang executable. Thank you for your response!

with the same question, I try

# cd into libquic
$find . -name '*.go'

and find out that lots of test file belongs libquic/boringssl use golang.

./boringssl/crypto/cipher/test/make_legacy_aead_tests.go
./boringssl/crypto/err/err_data_generate.go
./boringssl/ssl/test/runner/alert.go
./boringssl/ssl/test/runner/chacha20_poly1305.go
./boringssl/ssl/test/runner/chacha20_poly1305_test.go
...
...

and look inside libquic/boringssl/CMakeLists.txt, it will run these test file which written by golang.

So can we disable the tests to build without go?

@TomMD Yeah this seems wrong...

There is a "hard" dependency on go but there is no reason for it actually, after you generate the err_data.c you can skip test compilation for boringssl and there's zero dep after that on go. Really those files should be committed, or better yet convert the go script to a c program, then there's no weird dependency.

The usage of go is google fan-boy-ism at best, excessive pandering at worst.
