* [vcpkg docs] Change how documenting port functions works Instead of using `##`, use comment blocks for documentation. Also, add some minor docs and change RST -> MD so we actually get docs generated. * add CI stuff * regenerate docs * fix vcpkg_find_acquire_program to not use _execute_process

# 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.
|
|
|
|
