Ok I understand but your source package is meant to be built with
CMake too right?
So you have to handle the case "Am I" building from git source tree or from
"package source" tree from within your CMakeLists.txt ?
So you can perfectly add something like:
supposed GIT_TREE is true if your are configuring a git tree:
if (GIT_TREE)
configure_file(whatever.h.in ${CMAKE_CURRENT_BINARY_DIR}/whatever.h)
configure_file(whatever.h.in ${CMAKE_CURRENT_SOURCE_DIR}/whatever.h.srctree)
else(GIT_TREE)
configure_file(whatever.h.srctree
${CMAKE_CURRENT_BINARY_DIR}/whatever.h @COPYONLY)
endif(GIT_TREE)
the "whatever.h.srctree" is your generated file that will be package
with your source tree
but it will only be used if you are building from a non GIT source tree.
and... you can do out-of-source build in both cases.
concerning the fact that:

That's true but in any case you want your source package to contain the file
so the file WILL end up in the source tree when building from package
source right ?
