## # vcpkg_execute_in_download_mode
|
||
|
|
##
|
||
|
|
## Execute a process even in download mode.
|
||
|
|
##
|
||
|
|
## ## Usage
|
||
|
|
## ```cmake
|
||
|
|
## vcpkg_execute_in_download_mode(
|
||
|
|
## COMMAND <cmd> [<arguments>...]
|
||
|
|
## OUTPUT_QUIET ERROR_QUIET OUTPUT_STRIP_TRAILING_WHITESPACE ERROR_STRIP_TRAILING_WHITESPACE
|
||
|
|
## WORKING_DIRECTORY <dir>
|
||
|
|
## TIMEOUT <seconds>
|
||
|
|
## RESULT_VARIABLE <seconds>
|
||
|
|
## OUTPUT_VARIABLE <var_out>
|
||
|
|
## ERROR_VARIABLE <var_err>
|
||
|
|
## INPUT_FILE <f_in>
|
||
|
|
## OUTPUT_FILE <f_out>
|
||
|
|
## ERROR_FILE <f_err>
|
||
|
|
## ENCODING <enc>
|
||
|
|
## )
|
||
|
|
## ```
|
||
|
|
##
|
||
|
|
## The signature of this function is identical with `execute_process()` except that
|
||
|
|
## it only accepts one COMMAND argument, i.e., does not support chaining multiple
|
||
|
|
## commands with pipes.
|
||
|
|
##
|
||
|
|
## See `execute_process()` for a detailed description of the parameters.
