CMake does not require one specific location, it searches quite a few
locations. It is up to the project where it installs to, but I'd normally
recommend the place you are already using (${CMAKE_INSTALL_LIBDIR}/cmake/
<project-name>/). Have a look here for the full list (scroll down to the
list of directories starting with <prefix>/...):
https://cmake.org/cmake/help/latest/command/find_package.html
The only thing I could find that referred to a .../cmake3/ location was the
cmake3 package from epel, which I assume they do to avoid clashing with the
default cmake package. Personally, I'd consider that to be wrong behavior
though since CMake won't be searching that location by default (unless they
patched their cmake3 executable to search there as well, but still it's not
ideal).
