Summary0010468: find_program() doesn't find not readable programs on *nix
DescriptionSay, I'm trying to do find_program(SUDO NAMES sudo) and it fails while sudo is actually available and working.

find_program() calls cmSystemTools::FindProgram(), which in turn uses SystemTools::FileExists().
FileExists() calls "access(filename, R_OK)" to determine if the file is useful.
This is wrong, because a program may be not readable and still executable.
This is, for example, the case for setuid programs, as many distributions set ---s--x--x mode for them.

Also access() checks real user's permission instead of effective one.

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.
