Furthermore, the one file can tell CMake where to find all the
libraries, headers, resources, etc. that come with the package.  This
avoids accidental mismatches of header files and libraries.  Switching
from one installation of the package to another requires only one cache
variable to be changed.  Unlike pkgconfig the "one file" can just be
placed inside the package install tree instead of in a special location
in the prefix.  It can also do versioning (i.e. find version 4.1 of the
package).
