4.4.6.1 CMake Build Types

CMake has a CMAKE_BUILD_TYPE option for predefined build types. The build type affects optimization and whether the result of the build is debuggable. Those used by MySQL are RelWithDebInfo or Debug.

• RelWithDebInfo (optimizations are on, debug info is generated) is used in MySQL by default.

• Debug (optimizations are off, debug info is generated) is used if the WITH_DEBUG option is set.

• CMAKE_BUILD_TYPE is not set when custom compile flags are used (see Section 4.4.6.2, “How to Specify Compilers and Compiler Flags”).
