vcpkg_execute_required_process
The latest version of this document lives in the vcpkg repo.
Execute a process with logging and fail the build if the command fails.
Usage
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>]
[SAVE_LOG_FILES <relative-path> [ALIAS <unique-alias>] [<relative-path>...]]
)
Parameters
ALLOW_IN_DOWNLOAD_MODE
Allows the command to execute in Download Mode. See execute_process() override.
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.
SAVE_LOG_FILES
Optional files to be moved from the working directory to ${CURRENT_BUILDTREES_DIR}.
The files are copied even if the process failed.
This helps to collect relevant log files in CI setups.
The target filename is constructed from the LOGNAME parameter and the parameter of the ALIAS keyword following the source path.
If ALIAS is absent, the target filename is constructed from the LOGNAME parameter, the source filename,
and the suffix .log if the source filename doesn't already end with this suffix.
