Development/CMake/Build Types
< Development | CMake
CMake supports different build types for compiling the source code. The following built-in build types are available to the CMake buildsystem:
Note
- Release
- optimized for speed, no debug symbols or qDebug/kDebug messages, no asserts
- RelWithDebInfo
- similiar to release, but with debug symbols for backtraces (-g)
- Debug
- optimized for speed, but debuggable and with debug symbols for backtraces (-g)
- debugfull
- no optimizations, full debug support (-g3)
- Profile
- adds coverage flags (-ftest-coverage -fprofile-arcs) to debugfull
- None
- the build flags are manually set using the CMAKE_CXX_FLAGS option.
You can tell CMake the desired build type by passing the relevant type as command line option, for instance:
cmake /path/to/source -DCMAKE_BUILD_TYPE=debugfull
The default value is RelWithDebInfo.
