cmake: Use share instead of DATADIR for CMake config files

See the following discussion for context:
https://discourse.cmake.org/t/what-should-the-destination-be-for-a-header-only-librarys-cmake-config-file/8473/3

TLDR: `DATADIR` can be `share` but it doesn't have to be. It can
be changed by the user.
