It turns out that CMake always canonicalizes `CMAKE_INSTALL_PREFIX` to an absolute path--if it's a relative path, it canonicalizes it relative to the build directory. As a result, the only thing the DESTDIR and relative directory check prevents is an installation into the root directory since CMake strips the trailing slash, turning "/" into an empty string. Let's just remove the check all together, since it cannot accomplish what we intended.
