Heya,

Looks like you need to call ExternalProject_Add_Step() to create a custom \
step  for this. This function accepts 'ALWAYS'.

Signature:
ExternalProject_Add_Step(<name> <step>
 [COMMAND cmd...]
 [COMMENT "text..."]
 [DEPENDEES steps...]
 [DEPENDERS steps...]
 [DEPENDS files...]
 [ALWAYS 1]
 [WORKING_DIRECTORY dir]
)

See section 'Adding Custom Steps' in:
http://www.kitware.com/media/html/BuildingExternalProjectsWithCMake2.8.html

And then just set the 'DEPENDEES' parameter to build, in order to have it \
run  during the build phase.
