[CMake] How to suppress output like "-- Checking whether C ", etc.?

[Peng Yu]

Hi,

I just want "Hello World!" to be shown and everything else be
suppressed. "-Wno-dev" seems not relevant. I don't find other options
seem to be useful in the manual. In case I miss anything in the
manual, is there an option to suppress these messages? Thanks!

~/linux/test/cmake/lang/command/message/build$ cat ../src1/CMakeLists.txt
message("Hello World!")
~/linux/test/cmake/lang/command/message/build$ rm -rf *
~/linux/test/cmake/lang/command/message/build$ cmake ../src1/
