Background: while for autotools there are the ptx/endis, ptx/disen, and
ptx/wwo helpers, nothing comparable exists for cmake. For options
setting on cmake packages you can add those to FOO_CONF_OPT of your
package and currently there are for example those two ways:
ifdef PTXCONF_FOO_ENABLE_BAR
FOO_CONF_OPT += -DENABLE_BAR:BOOL=ON
else
FOO_CONF_OPT += -DENABLE_BAR:BOOL=OFF
endif
You could also use something shorter like:
FOO_CONF_OPT += -DENABLE_BAR=$(call ptx/ifdef, \
PTXCONF_FOO_ENABLE_BAR, ON, OFF)
With the new helper macro this will be even easier:
FOO_CONF_OPT += -DENABLE_BAR=$(call ptx/onoff, PTXCONF_FOO_ENABLE_BAR)
