## # vcpkg_fail_port_install
##
## Checks common requirements and fails the current portfile with a (default) error message
##
## ## Usage
## ```cmake
## vcpkg_fail_port_install(
## [ALWAYS]
## [MESSAGE <"Reason for failure">]
## [ON_TARGET <Windows> [<OSX> ...]]
## [ON_ARCH <x64> [<arm> ...]]
## [ON_CRT_LINKAGE <static> [<dynamic> ...]])
## [ON_LIBRARY_LINKAGE <static> [<dynamic> ...]]
## )
## ```
##
## ## Parameters
## ### MESSAGE
## Additional failure message. If none is given, a default message will be displayed depending on the failure condition.
##
## ### ALWAYS
## Will always fail early
##
## ### ON_TARGET
## Targets for which the build should fail early. Valid targets are `<target>` from `VCPKG_IS_TARGET_<target>` (see `vcpkg_common_definitions.cmake`).
##
## ### ON_ARCH
## Architecture for which the build should fail early.
##
## ### ON_CRT_LINKAGE
## CRT linkage for which the build should fail early.
##
## ### ON_LIBRARY_LINKAGE
## Library linkage for which the build should fail early.
##
## ## Examples
