Summary0010967: mark_as_advanced with find_program overwrites local variables on first CMake run
DescriptionThe mark_as_advanced function overwrites local variables on the first CMake invocation when find_program and mark_as_advanced are called multiple times. We observed this in the Titan project where MPIEXEC was set as a local variable, find_program didn't make a cache entry as MPIEXEC was defined, but mark_as_advanced did. The subsequent run of find_program then defined a type and overwrote the local variable (leaving an empty string).

I have attached two files, placed in the same directory you should be able to reproduce this error. I observed it on Windows with CMake 2.8.1 and on Linux with a fresh build of CMake master from today.
Steps To Reproduce
Additional InformationFirst CMake run,

MPIEXEC 1: No changing me!,
MPIEXEC 2: No changing me!, UNINITIALIZED
MPIEXEC 3: , FILEPATH

Second CMake run,

MPIEXEC 1: No changing me!, FILEPATH
MPIEXEC 2: No changing me!, FILEPATH
MPIEXEC 3: No changing me!, FILEPATH
TagsNo tags attached.

Unset target version field; too late for a fix to go into 2.8.7; deferred until a future version.

Sending old, not-recently-updated issues to the backlog.

(The age of the bug alone means that nobody is actively working on it...)

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 who has the bandwidth to take it on, and ferry a fix through to our 'next' branch for dashboard testing.
