			Build types can be added. I thought this might be useful for a <tt>Coverage</tt> target, but I ended up stuffing the coverage flags into <tt>CMAKE_C_FLAGS_DEBUG</tt>/<tt>CMAKE_CXX_FLAGS_DEBUG</tt>.

[https://gitlab.kitware.com/cmake/cmake CMake] is one of the numerous build systems that seeks to replace [[Autotools]]+[[Make]] in the twenty-first century.

			A CMake build can be configured on the command line with <tt>-D</tt> switches, or using <tt>ccmake</tt>/<tt>cmake-gui</tt>. Either way, the result is build infrastructure for some other tool, such as [[Make]] or [[Ninja]].

			==Build Types==
			<tt>CMAKE_BUILD_TYPE</tt> can take any of the values in <tt>CMAKE_CONFIGURATION_TYPES</tt>. Important ones include:
			* Debug -- no optimization, full debug info, <tt>assert</tt> (<tt>NDEBUG</tt> is not defined)
			* RelWithDebInfo -- optimized, symbols
			* Release -- optimized, no symbols
			* MinSizeRel -- optimized for size
