target_compile_options
----------------------

Add compile options to a target.

::

  target_compile_options(<target> [BEFORE] <INTERFACE|PUBLIC|PRIVATE> [items1...]
    [<INTERFACE|PUBLIC|PRIVATE> [items2...] ...])

Specify compile options to use when compiling a given target.  The
named <target> must have been created by a command such as
add_executable or add_library and must not be an IMPORTED target.  If
BEFORE is specified, the content will be prepended to the property
instead of being appended.

The INTERFACE, PUBLIC and PRIVATE keywords are required to specify the
scope of the following arguments.  PRIVATE and PUBLIC items will
populate the COMPILE_OPTIONS property of <target>.  PUBLIC and
INTERFACE items will populate the INTERFACE_COMPILE_OPTIONS property
of <target>.  The following arguments specify compile options.
Repeated calls for the same <target> append items in the order called.

Arguments to target_compile_options may use "generator expressions"
with the syntax "$<...>".
See the :manual:`cmake-generator-expressions(7)` manual for available
expressions.
