Summary0010515: cmake deletes output files from add_custom_command under XP
DescriptionHi,

I could only reproduces this under XP (I have only cmake 2.6 under fedora here), so this may be a single platform issue.

When using a setup like:

project(cmakeBug)

set(src ${PROJECT_SOURCE_DIR}/src)
set(inc ${PROJECT_SOURCE_DIR}/inc)

add_custom_command(OUTPUT ${inc}/test.h ${inc}/test2.h ${src}/test.c
        COMMAND echo "//foo" > ${inc}/test.h
        COMMAND echo "//foo" > ${inc}/test2.h
        COMMAND echo "//bar" > ${src}/test.c
)

add_executable(test ${src}/main.c ${src}/test.c)


The next call to cmake will remove the first output file (test.h in that case).
Note that this only happens for multiple output files.
TagsNo tags attached.

 This is intentional. If any output file does not exist we purposely delete the "primary" output file to ensure that the rule re-runs on the next build.

 Would be fine, if this would not happen when all output files do exist and are up-to-date ;)

 What happens if you add ${inc}/test.h to the executable sources?

add_executable(test ${src}/main.c ${src}/test.c ${inc}/test.h)

 Sending issues I'm not actively working on to the backlog to await someone with time for them.

If an issue you care about is sent to the backlog when you feel it should have been addressed in a different manner, please bring it up on the CMake mailing list for discussion. Sign up for the mailing list here, if you're not already on it:

 http://www.cmake.org/mailman/listinfo/cmake [^]

It's easy to re-activate a bug here if you can find a CMake developer or contributor who has the bandwidth to take it on.
