* [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_execute_required_process
|
|
|
|
Execute a process with logging and fail the build if the command fails.
|
|
|
|
## Usage
|
|
```cmake
|
|
vcpkg_execute_required_process(
|
|
COMMAND <${PERL}> [<arguments>...]
|
|
WORKING_DIRECTORY <${CURRENT_BUILDTREES_DIR}/${TARGET_TRIPLET}-dbg>
|
|
LOGNAME <build-${TARGET_TRIPLET}-dbg>
|
|
[TIMEOUT <seconds>]
|
|
[OUTPUT_VARIABLE <var>]
|
|
[ERROR_VARIABLE <var>]
|
|
)
|
|
```
|
|
## Parameters
|
|
### ALLOW_IN_DOWNLOAD_MODE
|
|
Allows the command to execute in Download Mode.
|
|
[See execute_process() override](../../scripts/cmake/execute_process.cmake).
|
|
|
|
### COMMAND
|
|
The command to be executed, along with its arguments.
|
|
|
|
### WORKING_DIRECTORY
|
|
The directory to execute the command in.
|
|
|
|
### LOGNAME
|
|
The prefix to use for the log files.
|
|
|
|
### TIMEOUT
|
|
Optional timeout after which to terminate the command.
|
|
|
|
### OUTPUT_VARIABLE
|
|
Optional variable to receive stdout of the command.
|
|
|
|
### ERROR_VARIABLE
|
|
Optional variable to receive stderr of the command.
|
|
|
|
This should be a unique name for different triplets so that the logs don't conflict when building multiple at once.
|
|
|
|
