CMAKE_OSX_SYSROOTΒΆ
Specify the location or name of the macOS platform SDK to be used.
CMake uses this value to compute the value of the -isysroot
flag
or equivalent and to help the find_*
commands locate files in
the SDK.
If not set explicitly the value is initialized by the SDKROOT
environment variable, if set, and otherwise computed based on the
CMAKE_OSX_DEPLOYMENT_TARGET
or 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.
