|
|
##
|
|
## 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.
|
|
