Add compile definitions to a target.
target_compile_definitions(<target> <INTERFACE|PUBLIC|PRIVATE> [items1...] [<INTERFACE|PUBLIC|PRIVATE> [items2...] ...])
Specifies compile definitions 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 ALIAS target.
The INTERFACE
, PUBLIC
and PRIVATE
keywords are required to specify the scope of the following arguments. PRIVATE
and PUBLIC
items will populate the COMPILE_DEFINITIONS
property of <target>
. PUBLIC
and INTERFACE
items will populate the INTERFACE_COMPILE_DEFINITIONS
property of <target>
. (IMPORTED targets only support INTERFACE
items.) The following arguments specify compile definitions. Repeated calls for the same <target>
append items in the order called.
Arguments to target_compile_definitions
may use “generator expressions” with the syntax $<...>
. See the cmake-generator-expressions(7)
manual for available expressions. See the cmake-buildsystem(7)
manual for more on defining buildsystem properties.
Any leading -D
on an item will be removed. Empty items are ignored. For example, the following are all equivalent:
target_compile_definitions(foo PUBLIC FOO) target_compile_definitions(foo PUBLIC -DFOO) # -D removed target_compile_definitions(foo PUBLIC "" FOO) # "" ignored target_compile_definitions(foo PUBLIC -D FOO) # -D becomes "", then ignored
