If you want to compile TDLib for 64-bit Java on Windows using MSVC, you will also need to add `-A x64` option to CMake.
In Windows, use Vcpkg toolchain file by adding parameter -DCMAKE_TOOLCHAIN_FILE=<VCPKG_DIR>/scripts/buildsystems/vcpkg.cmake
Then you can build this example:

If you get "Could NOT find JNI ..." error from CMake, you need to specify to CMake path to the installed JDK, for example, "-DJAVA_HOME=/usr/lib/jvm/java-8-oracle/".
If you get java.lang.UnsatisfiedLinkError with "Can't find dependent libraries", you may also need to copy some dependent shared libraries to `bin/`.
If you get java.lang.UnsatisfiedLinkError with "Can't find dependent libraries", you may also need to copy some dependent shared libraries to bin/.
In case you compiled the example as 32-bit version, you may need to give -d32 parameter to Java.
