Summary0014961: CMake doesn't warn about function redefinition
DescriptionCMake doesn't prevent or produce a warning/error when redefining functions which is very error prone. For example introducing a conflicting function definition in a subproject can easily break the build of the main project.
Steps To ReproduceConsider the following test project:

CMakeLists.txt:

cmake_minimum_required(VERSION 2.8)
function(test)
  message("parent")
endfunction()
add_subdirectory(sub)
test()

sub/CMakeLists.txt:

function(test)
  message("sub")
endfunction()

Running cmake prints "sub" which means that the test function defined in sub/CMakeLists.txt is used and not in CMakeLists.txt. No warnings or error message is produced.
