CMAKE_SYSROOTΒΆ
Path to pass to the compiler in the --sysroot flag.
The CMAKE_SYSROOT content is passed to the compiler in the --sysroot
flag, if supported. The path is also stripped from the RPATH/RUNPATH if
necessary on installation. The CMAKE_SYSROOT is also used to prefix
paths searched by the find_* commands.
This variable may only be set in a toolchain file specified by
the CMAKE_TOOLCHAIN_FILE variable.
See also the CMAKE_SYSROOT_COMPILE and
CMAKE_SYSROOT_LINK variables.
