## [CMake 3.25][cmake master]: WIP ## [CMake 3.25][cmake master]: Blocks and SYSTEM
CMake has new block scoping commands selectively controlling variables and
policies. It also has a lot more control over SYSTEM. The functional features
of CMake introduced a few releases ago are now usable in `find_` commands with
`VALIDATOR`. Workflows got an upgrade, too.
- C++26 support - C++26 support
- LTO for CUDA with nvcc - LTO for CUDA with nvcc
- Workflow presets added - Workflow presets added, package presets too.
- `SYSTEM` added to `add_subdirectory`, `FetchContent`, and as a directory property - `SYSTEM` added to `add_subdirectory`, `FetchContent`, and as a directory property
- `block()`/`endblock()` for policy/variable scopes, also `PROPOGATE` in `return()`
- `BSD` & `LINUX` variables added - `BSD` & `LINUX` variables added
- `VALIDATOR` function for `find_*` commands.
- Several improvements to `try_*` commands.
- `SYSTEM` target/directory property and `EXPORT_NO_SYSTEM` added, also for FetchContent.
-## [CMake in development][cmake master]: WIP
