## [CMake 3.22][]: Handy env vars
A smaller release with some nice improvements all around focused on supporting
common build situations. You can finally set `CMAKE_BUILD_TYPE` in your
environment to set a default build type. There are several other new env vars
and variables too. Compiler flags related to standards have been improved.
`cmake_host_system_information` got improved further (from 3.10) with OS
information.

* New environment variable `CMAKE_INSTALL_MODE` for install types (symlinks)

* `CMAKE_<LANG>_EXTENSIONS_DEFAULT` comes from the compiler
* `CMakeDependentOption` uses normal conditional syntax now
* CTest can now modify environment variables
* Some generators now use external (system) markers on includes for MSVC
