$ cmake ..

WARNING: Target "bar" has EXCLUDE_FROM_ALL set and will not be built by
default but an install rule has been provided for it. CMake does not define
behavior for this case.

$ cat ../CMakeLists.txt
cmake_minimum_required(VERSION 2.8)
project(foo C)
add_executable(bar EXCLUDE_FROM_ALL bar.c)
install(TARGETS bar DESTINATION bin OPTIONAL)
Maybe CMake _should_ define the obvious behaviour and get rid of this message.
BTW: "make install bar" shows the behaviour but maybe the OP just wanted
"make bar install" instead ;)
Or better "make bar && make install" when having MAKEFLAGS set to -j2.
