Hi,

I am trying to force the BUILD step of an ExternalProject_Add target to be =
run - always. I have found several wiki articles, and references in the arc=
hives of this list, to setting an ALWAYS option for the stage I want to for=
ce to run each time. The problem is I can=92t find any documentation on the=
 exact syntax to use - can someone please enlighten me? (This is for a proj=
ect where the files are on the local disk when the build is run, but may ch=
ange due to external sync mechanisms - right now the build system never not=
ices this)

I=92m guessing it must be something like:

ExternalProject_Add(Foo =

   PREFIX ${CMAKE_BINARY_DIR}
   DOWNLOAD_COMMAND ""    # no need to download
   BUILD_ALWAYS # <<< but is this correct?
   SOURCE_DIR ${CMAKE_CURRENT_LIST_DIR}/path/to/foo
  =85...
)

Kind regards,
James Turner =
