Hi all,
I'm trying to write a custom command that will run a CMake script to add some
content in a file. Problem is, if I'm building with multiple process enabled in
Visual Studio project, and the custom command is added to a few different
CMakeLists.txt files, I get synchronizations issues.
In my a bunch of CMakeLists.txt I have:
add_custom_command(TARGET ${PROJECT_NAME} POST_BUILD COMMAND ${CMAKE_COMMAND}
ARGS -P "file_append.cmake")
In file_append.cmake I have:
file(APPEND "output.txt" "some content\n")
When looking at the content of output.txt, we see that some lines are
truncated, half-written or skipped entirely. Is there a way to make the file
command lock the file during the append so that multiple process sharing some
modifiable resource do not run into conflict between each other? I saw the
file(LOCK...) command but it doesn't seems to work for this case?
Thanks!
