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 archives of
this list, to setting an ALWAYS option for the stage I want to force to run
each time. The problem is I can’t find any documentation on the exact syntax to
use - can someone please enlighten me? (This is for a project where the files
are on the local disk when the build is run, but may change due to external
sync mechanisms - right now the build system never notices this)
I’m 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
…...
)
Kind regards,
James Turner
