target_compile_features¶
Added in version 3.1.
Add expected compiler features to a target.
target_compile_features(<target> <PRIVATE|PUBLIC|INTERFACE> <feature> [...])
Specifies compiler features required when compiling a given target. If the
feature is not listed in the CMAKE_C_COMPILE_FEATURES,
CMAKE_CUDA_COMPILE_FEATURES, or CMAKE_CXX_COMPILE_FEATURES
variables, then an error will be reported by CMake. If the use of the feature requires
an additional compiler flag, such as -std=gnu++11, the flag will be added
automatically.
The INTERFACE, PUBLIC and PRIVATE keywords are required to
specify the scope of the features. PRIVATE and PUBLIC items will
populate the COMPILE_FEATURES property of <target>.
PUBLIC and INTERFACE items will populate the
INTERFACE_COMPILE_FEATURES property of <target>.
Repeated calls for the same <target> append items.
Added in version 3.11: Allow setting INTERFACE items on IMPORTED targets.
The named <target> must have been created by a command such as
add_executable() or add_library() and must not be an
ALIAS target.

Arguments to target_compile_features may use generator expressions
with the syntax $<...>. See the cmake-generator-expressions(7)
manual for available expressions. See the cmake-compile-features(7)
manual for information on compile features and a list of supported compilers.
