Subject: [PATCH] Use relative install paths for CMake

Files are installed via a special _PREFIX variant of the INSTALL_???_DIR
variable which is an absolute path.

This not only is redundant if CMAKE_INTALL_PREFIX is set but it even causes
the resulting Config.cmake to be non relocatable. This means it contains absolute
paths to the build host. This is a problem for cross compilation in Yocto.

This change gets rid of the absolute path and removes the no longer needed
_PREFIX variants.

Upstream-Status: Submitted [https://github.com/libyui/libyui/pull/140]
