If a port has a dependency on itself, as a host dependency, then if the host build fails, the non-host build will still run:
Let ports be:
ports/
a/
vcpkg.json
portfile.cmake
with ports/a/vcpkg.json:
{
"name": "a",
"version": "0",
"dependencies": [
{
"name": "a",
"host": true
}
]
}and ports/a/portfile.cmake:
if(TARGET_TRIPLET STREQUAL HOST_TRIPLET)
message(FATAL_ERROR boop)
endif()
Then, run vcpkg ci x64-osx --debug on an arm64-osx machine, and you will get the following:
PS /../nimazzuc/projects/vcpkg> ./vcpkg ci x64-osx --debug
