## Default build type
CMake normally does a "non-release, non debug" empty build type; if you prefer to set the default build type yourself, you can follow this
recipe for the default build type modified from the [Kitware blog ](https://blog.kitware.com/cmake-and-the-default-build-type/ ):
```cmake
set(default_build_type "Release")
if(NOT CMAKE_BUILD_TYPE AND NOT CMAKE_CONFIGURATION_TYPES)
message(STATUS "Setting build type to '${default_build_type}' as none was specified.")
set(CMAKE_BUILD_TYPE "${default_build_type}" CACHE
STRING "Choose the type of build." FORCE)
# Set the possible values of build type for cmake-gui
set_property(CACHE CMAKE_BUILD_TYPE PROPERTY STRINGS
"Debug" "Release" "MinSizeRel" "RelWithDebInfo")
endif()
```
