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

[Attila Krasznahorkay]

Hi Isaac,

ccmake will only allow you to modify cache variables. When you call

set( CMAKE_BUILD_TYPE RelWithDebInfo )

, this creates a local variable in your CMakeLists.txt file. This way it should 
*always* override whatever you set on the command line, or as a cache variable.

If you want to set the default value to RelWithDebInfo, but allow the user to 
override it either with ccmake or a command line argument, you should do 
something like:

set( CMAKE_BUILD_TYPE RelWithDebInfo CACHE STRING "Build type" )

At least I think it should work like this...

Cheers,
  Attila

[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!
