If <tt>CMAKE_BUILD_TYPE</tt> is not provided, none of these is used -- no debugging flags are set, and no optimization flags are set, in a somewhat stunning bit of unexpected behavior. The following snippet will ensure a default, and allow the value to be selected from a set in the gui: | |||
<pre> | |||
# Set a default build type if none was specified | |||
set(default_build_type "Release") | |||
if(EXISTS "${CMAKE_SOURCE_DIR}/.git") | |||
set(default_build_type "Debug") | |||
endif() | |||
if(NOT CMAKE_BUILD_TYPE AND NOT CMAKE_CONFIGURATION_TYPES) | |||
message(STATUS "Setting build type to '${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() | |||
</pre> | |||
