#[===[.md:
# vcpkg_execute_build_process
Execute a required build process
## Usage
```cmake
vcpkg_execute_build_process(
COMMAND <cmd> [<args>...]
[NO_PARALLEL_COMMAND <cmd> [<args>...]]
WORKING_DIRECTORY </path/to/dir>
LOGNAME <log_name>
)
```
## Parameters
### COMMAND
The command to be executed, along with its arguments.
### NO_PARALLEL_COMMAND
Optional parameter which specifies a non-parallel command to attempt if a
failure potentially due to parallelism is detected.
### WORKING_DIRECTORY
The directory to execute the command in.
### LOGNAME
The prefix to use for the log files.
This should be a unique name for different triplets so that the logs don't
conflict when building multiple at once.
## Examples
* [icu](https://github.com/Microsoft/vcpkg/blob/master/ports/icu/portfile.cmake)
