Well, this just has the following:
IF(NOT CMAKE_INSTALL_COMPONENT OR "${CMAKE_INSTALL_COMPONENT}" STREQUAL
"Unspecified")
EXECUTE_PROCESS (
COMMAND ant ...
WORKING_DIRECTORY /home/david/src/java
#OUTPUT_VARIABLE _out
ERROR_VARIABLE _err
#RESULT_VARIABLE _res
)
MESSAGE( FATAL_ERROR "err: ")
ENDIF(NOT CMAKE_INSTALL_COMPONENT OR "${CMAKE_INSTALL_COMPONENT}" STREQUAL
"Unspecified")
IF(NOT CMAKE_INSTALL_COMPONENT OR "${CMAKE_INSTALL_COMPONENT}" STREQUAL
"Unspecified")
MESSAGE("out: , err: , res: ...")
ENDIF(NOT CMAKE_INSTALL_COMPONENT OR "${CMAKE_INSTALL_COMPONENT}" STREQUAL
"Unspecified")
So it looks like the variable(s) is(are) being expanded (in the first case)
prior to running the 'ant' command. Any ideas why this might be?
Thanks,
-David
PS: I'm surprised that this isn't something that many, many CMake authors
need/require (i.e., the ability to terminate or otherwise operate on the
results of an "install code..." sequence). Especially given the availability of
the error, output, and result variable arguments to the execute_process
command. What is the proper syntax/pattern for this?
