Compilation:

(0) make sure that you had installed Android-NDK toolchain 
    and that you added the corresponding /bin folder to your %PATH% in Windows settings
    as well as you have android.toolchain.cmake downloaded and saved in known
    location (if you do not have, you can download it from
    https://github.com/taka-no-me/android-cmake)
(1) run CMake GUI, select folder with source code, (make and) select the folder in
    which the build will be created
(2) in CMake GUI add entry PATH > ANDROID_NDK and select the path
(3) in CMake GUI add entry STRING > ANDROID_ABI and input "x86_64"
(4) in CMake GUI confirm "configure", select "MinGW makefiles", "specify toolchain",
    select previously downloaded android.toolchain.cmake
(5) in CMake GUI set the option checkboxes to following values
    BUILD_DOCS		yes
    BUILD_EXAMPLES	yes
    BUILD_GUI		no
    BUILD_MIXED		no
    BUILD_SHARED	no (of extraordinary importance)
    BUILD_TESTING	yes
    WITH_INCHI		no
    WITH_JSON		yes
    WITH_STATIC_INCHI	no
    WITH_STATIC_LIBXML	no
    and delete items ZLIB_INCLUDE_DIR, ZLIB_LIBRARY_DEBUG, ZLIB_LIBRARY_RELEASE;
    add manually switch "-pie" to all items ending by "_FLAGS"
(6) in CMake GUI execute "configure" (again) and then "generate"
(7) open each file named "link.txt" and delete there "-fPIE" and "-pie"
    (because linking library by ar is not possible with switch "-pie")
(8) save all files, open cmd and run the compilation by
    mingw32-make
(9) resulting libraries and binaries will appear inside of the corresponding
    subfolders inside of the release folder
