CMAKE_OSX_DEPLOYMENT_TARGETΒΆ
Specify the minimum version of the target platform (e.g. macOS or iOS)
on which the target binaries are to be deployed. CMake uses this
variable value for the -mmacosx-version-min
flag or their respective
target platform equivalents. For older Xcode versions that shipped
multiple macOS SDKs this variable also helps to choose the SDK in case
CMAKE_OSX_SYSROOT
is unset.
If not set explicitly the value is initialized by the
MACOSX_DEPLOYMENT_TARGET
environment variable, if set,
and otherwise computed based on the host platform.
The value of this variable should be set prior to the first
project()
or enable_language()
command invocation
because it may influence configuration of the toolchain and flags.
It is intended to be set locally by the user creating a build tree.
This variable should be set as a CACHE
entry (or else CMake may
remove it while initializing a cache entry of the same name) unless
policy CMP0126
is set to NEW
.
Despite the OSX
part in the variable name(s) they apply also to
other SDKs than macOS like iOS, tvOS, or watchOS.
This variable is ignored on platforms other than Apple.
