Are you using "make -j" for parallel builds by any chance? Does it still
happen if you use make without any -j flags...?
Rather than:
ADD_CUSTOM_COMMAND(
OUTPUT ${outputlist}
COMMAND ${CMAKE_COMMAND} -P
${CMAKE_CURRENT_BINARY_DIR}/${targetprefix}.cmake
DEPENDS ${${datalist}}
I would recommend changing to:
ADD_CUSTOM_COMMAND(
OUTPUT ${CMAKE_CURRENT_BINARY_DIR}/${targetprefix}.sentinel
COMMAND ${CMAKE_COMMAND} -P
${CMAKE_CURRENT_BINARY_DIR}/${targetprefix}.cmake
COMMAND ${CMAKE_COMMAND} -E
${CMAKE_CURRENT_BINARY_DIR}/${targetprefix}.sentinel
DEPENDS ${${datalist}}
And then change anything that depends on ${outputlist} (if anything) to
depend on the sentinel file instead...
We use the "single output sentinel file" approach with the
ExternalProject_Add custom commands, and it works very well.
Perhaps multiple cmakes are trying to copy the same file at the same time
because of parallel building and multiple outputs being specified for the
add_custom_command call.... (Speculation) But if true, this might be a
reasonable explanation. If not, it's a mystery then....
Do you see any error output...? What is the "not terminating" thing: is it
that make never comes back, or that you have a zombie cmake process after
running make...?
