cmake_modules/FindSqlite3.cmake breaks transitive dependencies.

[dg0yt]

Since CMake 3.14, there is an official FindSQLite3.cmake, variable prefix SQLite3, and an imported target.
rtabmap comes with FindSqlite3.cmake, variable prefix Sqlite3.
On case-insensitive filesystems (Windows), this can break finding downstream dependencies with find_dependency(SQLite3). This was noticed in vcpkg when updating PROJ, via a rtabmap > opencv > vtk > proj > sqlite3 dependency chain.

CMake Error at C:/a/1/s/scripts/buildsystems/vcpkg.cmake:859 (_find_package):
  Found package configuration file:

    D:/installed/x64-windows/share/proj/proj-config.cmake

  but it set PROJ_FOUND to FALSE so package "PROJ" is considered to be NOT
  FOUND.  Reason given by package:

  PROJ could not be found because dependency SQLite3 could not be found.

Possible solutions:

• Move to a more distinct module name.
• Switch to the official module. Needs CMake 3.14.

I implemented the second suggestion. You could try this tag 0.21.4.1 on your pull request.

I didn't update my PR which discovered the problem, but I'm building successfully with 0.21.4.1 in a more general review of the vcpkg port, microsoft/vcpkg#37651.
