# CUDA_EXTENSIONS

New in version 3.8.

Boolean specifying whether compiler specific extensions are requested.

This property specifies whether compiler specific extensions should be used. For some compilers, this results in adding a flag such as `-std=gnu++11` instead of `-std=c++11` to the compile line. This property is `ON` by default. The basic CUDA/C++ standard level is controlled by the `CUDA_STANDARD` target property.

See the `cmake-compile-features(7)` manual for information on compile features and a list of supported compilers.

This property is initialized by the value of the `CMAKE_CUDA_EXTENSIONS` variable if set when a target is created and otherwise by the value of `CMAKE_CUDA_EXTENSIONS_DEFAULT` (see `CMP0128`).
