Extend the interface of the target_compile_features command with PUBLIC and INTERFACE keywords. Populate the INTERFACE_COMPILER_FEATURES target property if they are set. Consume the INTERFACE_COMPILER_FEATURES target property from linked dependent targets to determine the final required compiler features and the compile flag, if needed. Use the same pattern of origin-debugging which is used for other build properties.

INTERFACE_COMPILE_FEATURES
|
|
--------------------------
|
|
|
|
List of public compile requirements for a library.
|
|
|
|
Targets may populate this property to publish the compiler features
|
|
required to compile against the headers for the target. Consuming
|
|
targets can add entries to their own :prop_tgt:`COMPILE_FEATURES`
|
|
property such as ``$<TARGET_PROPERTY:foo,INTERFACE_COMPILE_FEATURES>``
|
|
to require the features specified in the interface of ``foo``.
|
|
|
|
Contents of ``INTERFACE_COMPILE_FEATURES`` may use "generator expressions"
|
|
with the syntax ``$<...>``. See the :manual:`cmake-generator-expressions(7)`
|
|
manual for available expressions.
