[CMake] I can not set CMAKE_BUILD_TYPE in CMakeList.txt

[Isaac Ge]

Hi anyone, I find the `set(CMAKE_BUILD_TYPE RelWithDebInfo)` in
CMakeList.txt does not work, because the actual build type show by ccmake
is empty. So I have to enter the correct build type in ccmake or add
command argument `-D CMAKE_BUILD_TYPE=RelWithDebInfo` while cmake.

Any idea? Thank you!
