cmake: Build configuration type doesnt influence CMake variables

cmake 3.18, Ubuntu 20.04

Choosing Projects->Build Settings -> Edit build configuration wont change CMake variables.

For example: Edit build configuration -> Release

Would have

• CMAKE_BUILD_TYPE is empty

 Only when Initial CMake parameters contains

-DCMAKE_BUILD_TYPE:STRING=Debug/Release before loading the project, is the CMAKE_BUILD_TYPE set as it should be.

Changing the build configuration should change the CMAKE_BUILD_TYPE as well.
