What is the magic behind vcpkg_test_cmake()?

[joa-quim]

I am trying to write a portfile to a new package. Managed to make it build but can't pass the vcpkg_test_cmake(PACKAGE_NAME GMT MODULE) step. No matter what I try

CMake integration test failed; unable to find_package(GMT MODULE REQUIRED)

And if I try with no call to vcpkg_test_cmake(PACKAGE_NAME GMT MODULE) than it fails because
(so I'm screw in either way)

-- Performing post-build validation done
Error: Building package gmt:x64-windows failed with: POST_BUILD_CHECKS_FAILED
Please ensure you're using the latest portfiles with `.\vcpkg update`, then
submit an issue at https://github.com/Microsoft/vcpkg/issues including:
  Package: gmt:x64-windows
  Vcpkg version: 2018.11.23-nohash

You can take a glance at vcpkg/buildtrees/gmt/x64-windows-test.

I also tried to decode that but no way. I think found the issue. My project produces exes and that is the reason why it fails the consistency check, but the error message is completely uninformative about it. The only thing one sees is that all build correctly but the install fails for an obscure reason.

This should be fixed in #5574.

vcpkg_test_cmake disabled now, and the error message friendly informed user to remove .exe or debug/include etc. Related to https://github.com/microsoft/vcpkg/blob/master/docs/examples/packaging-zipfiles.md
