However, that is wrong since that command currently needs two arguments
even if
one of them is empty. So instead I need the generated command to be
./test-drv-info "temporary_target_" ps >
/home/software/plplot/HEAD/build_dir/drivers/test_dyndrivers_dir/ps.driver_info
or
./test-drv-info "" ps >
/home/software/plplot/HEAD/build_dir/drivers/test_dyndrivers_dir/ps.driver_info
depending on how LIBRARY_TARGET_PREFIX is set.
Is it possible to implement that?
Hi Alan,
with VERBATIM just using regular unescaped quotes (which are cmake syntax and
not part of the value) around the argument should work e.g.
COMMAND test-drv-info "${LIBRARY_TARGET_PREFIX}" ${SOURCE_ROOT_NAME}
${CMAKE_CURRENT_BINARY_DIR}/test_dyndrivers_dir/${SOURCE_ROOT_NAME}.driver_info
That way even when ${LIBRARY_TARGET_PREFIX} expands empty
add_custom_command() will receive an argument which it will escape / quote as
required by the build system.
Hi Nils:
When starting fresh with a clean cache using
"${LIBRARY_TARGET_PREFIX}" in the COMMAND worked perfectly, i.e.,
propagated as "" to the command line when ${LIBRARY_TARGET_PREFIX}
expands empty. Thanks for that suggestion!
The strange thing is I am virtually positive I tried that exact idea
earlier today, and it did not work, but maybe that was due to another
issue such as a dirty cache.
Alan
