When these variables are set in the cache, changing the
CMAKE_INSTALL_PREFIX does not change the directories that actually get
used. Instead, use them if the user provided them via -D, otherwise use
the default based on CMAKE_INSTALL_PREFIX.
zlib is a compile library and its .pc file should live in the library
directory. This allows a 64bit zlib and a 32bit zlib to co-exist in the
same install prefix.
set(INSTALL_MAN_DIR "${CMAKE_INSTALL_PREFIX}/share/man" CACHE PATH "Installation directory for manual pages")
set(INSTALL_PKGCONFIG_DIR "${CMAKE_INSTALL_PREFIX}/share/pkgconfig" CACHE PATH "Installation directory for pkgconfig (.pc) files")
if (NOT INSTALL_BIN_DIR)
set(INSTALL_BIN_DIR "${CMAKE_INSTALL_PREFIX}/bin")

Even better would be to remove ${CMAKE_INSTALL_PREFIX}/ here completely. CMake will add it at install time for any relative path.
