CMAKE_STAGING_PREFIX¶
This variable may be set to a path to install to when cross-compiling. This can
be useful if the path in CMAKE_SYSROOT is read-only, or otherwise
should remain pristine.
The CMAKE_STAGING_PREFIX location is also used as a search prefix
by the find_* commands. This can be controlled by setting the
CMAKE_FIND_NO_INSTALL_PREFIX variable.
If any RPATH/RUNPATH entries passed to the linker contain the
CMAKE_STAGING_PREFIX, the matching path fragments are replaced
with the CMAKE_INSTALL_PREFIX.
