CMAKE_STAGING_PREFIX — CMake 3.7.2 Documentation

# 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`.
