Building OpenSSL libraries for Android, from windows

[elfietro]

Hello,
I have a simple chat program that uses OpenSSL
It works fine on windows, but I want to deploy it on android.
I tried to build the libcrypto and libssl libraries for android.

I got the information how to to it in linux here:
http://qt-project.org/doc/qt-5/opensslsupport.html

but if I go to the OpenSSL source directory, Configure is not recognized anymore
if I use the full path (C:\Qt\Qt5.2.1\5.2.1\Src\qtbase\configure.bat)
it says "andriod is an unknown option" (android-armv7 also)
I do not have a "make" or "build_lib" in windows equivalent to the scripts in linux.
how does configure know in which directory im am configuring?
how do I compile those openSSL sources to libcrypto.so and libssl.so (or libcrypto.lib and libssl.lib) from windows command prompt, so that I can package them into my APK for android?
what is the difference between .so libraries and .lib libraries?

please help! I am coming from visual studio and never did anything outside windows!

ok I downloaded the Msys shell,
and I see the script Configure in the OpenSSL-Source directory
but when i run it with "./Configure shared android" it gives me:
./Configure: line 2: exec: perl: not found

still need help!

ok i needed to install perl for windows, which I did (ActivePerl)
now next problem, when i use make build_libs: gcc.exe: error: unrecognized command line option '-mandroid'

here is complete output:

$ make build_libs
making all in crypto...

ok, I was using wrong GCC.exe or G++.exe compiler
I adjusted my $PATH variable to include :
C:\android\AndroidNDK\toolchains\arm-linux-androideabi-4.6\prebuilt\windows-x86_64\arm-linux-androideabi\bin

libcrypto.so and libssl.so are now created.
