# This function wraps COMMAND with cmake script, that makes possible standalone run with external
# arguments.
#
# Generated wrapper will be written to OUTPUT_FILE.
# If WORKING_DIRECTORY is not set COMMAND will be executed in CMAKE_CURRENT_BINARY_DIR.
# Variables from ENVIRONMENT will be set before COMMAND execution.
# PRE_RUN and POST_RUN arguments may contain extra cmake code that supposed to be executed before
# and after COMMAND, respectively. Both arguments accept a list of cmake script language
# constructions. Each item of the list will be concantinated into single string with '\n' separator.
# COMMAND_ECHO option takes a value like it does for execute_process, and passes that value to
# execute_process.
