# Choose the type of build. CMake has default flags for these:
|
|
#
|
|
# * None (CMAKE_C_FLAGS or CMAKE_CXX_FLAGS used)
|
|
# * Debug (CMAKE_C_FLAGS_DEBUG or CMAKE_CXX_FLAGS_DEBUG)
|
|
# * Release (CMAKE_C_FLAGS_RELEASE or CMAKE_CXX_FLAGS_RELEASE)
|
|
# * RelWithDebInfo (CMAKE_C_FLAGS_RELWITHDEBINFO or CMAKE_CXX_FLAGS_RELWITHDEBINFO
|
|
# * MinSizeRel (CMAKE_C_FLAGS_MINSIZEREL or CMAKE_CXX_FLAGS_MINSIZEREL)
|
