## # vcpkg_fail_port_install
##
## Fails the current portfile with a (default) error message
##
## ## Usage
## ```cmake
## vcpkg_fail_port_install([MESSAGE <message>] [ON_TARGET <target1> [<target2> ...]]
## [ON_ARCH <arch1> [<arch2> ...]]
## [ON_CRT_LINKAGE <link1> [<link2> ...]])
## [ON_LIBRARY_LINKAGE <linklib1> [<linklib2> ...]])
## ```
##
## ## Parameters
## ### MESSAGE
## Additional failure message. If non 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
