No, I really do mean ERROR_VARIABLE (unless, of course, this variable does not
include the non-zero exit status of the EXECUTE_PROCESS command?).
BTW, I'm still curious about the (dual 'code') construct generally.
Specifically, if I do the following I never see the fatal error message (so I'm
wondering if there's still something wrong regarding the scoping of the message
command)?
install (CODE "EXECUTE_PROCESS (
COMMAND ant ...
WORKING_DIRECTORY ${PROJECT_SOURCE_DIR}/java
ERROR_VARIABLE _err
)
MESSAGE( FATAL_ERROR \"err: ${_err}\")
BTW, the following doesn't work either (each of the variables is empty):
install (CODE "EXECUTE_PROCESS (
COMMAND ant ...
WORKING_DIRECTORY ${PROJECT_SOURCE_DIR}/java
OUTPUT_VARIABLE _out
ERROR_VARIABLE _err
RESULT_VARIABLE _res
)
Install (CODE "MESSAGE( STATUS \"out: ${_out}, err: ${_err}, res:
${_res}...\")")
