[CMake] How to disable the CPack preinstall build?

[Craig Scott]

Good chance CMAKE_BUILD_WITH_INSTALL_RPATH
<https://cmake.org/cmake/help/latest/variable/CMAKE_BUILD_WITH_INSTALL_RPATH.html>
may
be what you are looking for. There's also always the option of just running
cpack directly rather than "make package" (not sure if that will avoid the
part of the process that is causing you problems though).
