Bug 306600

Following CMakeLists.txt produces "wrong-target" in Projects Tool View:

# ===== BEGIN =====
cmake_minimum_required(VERSION 2.8)
project(bug_demo)

function(Executable name)
    set_property(DIRECTORY APPEND PROPERTY ${name}_EXE_SOURCES ${ARGN})
    get_property(sources DIRECTORY PROPERTY ${name}_EXE_SOURCES)

    # Using of ADD_LIBRARY() instead of ADD_EXECUTABLE() adds a valid target (but without source files attached to it):
    #add_library(${name} ${sources})
    add_executable(${name} ${sources})

endfunction(Executable)

Executable(wrong_target_bug main.cpp)
# ===== END =====

main.cpp may be any hello-world sample:

#include <iostream>
int main(int argc, char **argv) { std::cout << "Hello, world!" << std::endl; return 0; }


Reproducible: Always

Steps to Reproduce:
1. Create project with specified CMakeLists.txt and main.cpp
2. Look at Project Tool View

Actual Results:  
"|wrong-target" displayed

Expected Results:  
target named "bug_demo"

Looks similiar to bug 293750, but is more general and different/simple way to reproduce.
As written in comments, using of ADD_LIBRARY() instead of ADD_EXECUTABLE() adds a valid target (but without source files attached to it)
