README: add a section about CMake exported targets.

Browse Source 
Since it's a new feature, we may as well write about it, even though I
would personally not recommend this in favor of more standard and
generic pkg-config (which is not dependent on which build system we are
using ourselves).

### Build with CMake exported targets
uchardet installs a standard pkg-config file which will make it easily
discoverable by any modern build system. Nevertheless if your project also uses
CMake and you want to discover uchardet installation using CMake exported
targets, you may find and link uchardet with:
```
project(sample LANGUAGES C)
find_package ( uchardet )
if (uchardet_FOUND)
add_executable( sample sample.c )
target_link_libraries ( sample PRIVATE uchardet::libuchardet )
endif ()
```
Note though that we recommend the library discovery with `pkg-config` because it
is standard and generic. Therefore it will always work, even if we decided to
change our own build system (which is not planned right now, but may always
happen). This is why we advise to use standard `pkg-config` discovery.
Some more CMake specificities may be found in the [commit
message](https://gitlab.freedesktop.org/uchardet/uchardet/-/commit/d7dad549bd5a3442b92e861bcd2c5cda2adeea27)
which implemented such support.
