How to deploy GoLang Binaries to CF - go

Question

Hi we are trying to deploy golang binaries to cf.
for example main.exe which is in /deploy/ folder along with mainfest file
Note: It is also observed that if we push the whole project app then it works. but if we try to push only binaries then we get the below error
And Manifest file contains following info
applications:
- name: test-app
command: test-app
env:
GO_INSTALL_PACKAGE_SPEC: ./
**ERROR** To use go native vendoring set the $GOPACKAGENAME
environment variable to your app's package name
**ERROR** Unable to determine import path: GOPACKAGENAME unset
After adding GOPACKAGENAME: main since main.exe is our binary name we get following error below
Failed to compile droplet: Failed to run finalize script: exit status 12

thanks #Volker for pointing out
for above issue:
first we have to build with following command (used make file)
GOOS="linux" go build main.go
then copy that main binary to /deploy folder
then manifest file in the deploy folder
applications:
- name: test-app
command: ./main
stack: cflinuxfs3
buildpacks:
- https://github.com/cloudfoundry/binary-buildpack.git
Then to push to cf
cf push -f ./manifest-template.yml
