Issue title: megacmd doesn't want to be compiled
 Issue body: Good Day.  A couple of weeks ago I discovered this wonderful application.  I immediately installed ubuntu on top of termux/android, found all the libraries, compiled. And it worked wonderfully until  started to say that a second instance of the server is running.  I tinkered a bit with this problem, quickly found no answer and decided to rebuild the application.  But since this did not help, reinstalled the ubuntu.  And that’s all.  I have never succeeded in compiling megacmd anymore.  Dances with a tambourine began.  I reinstalled ubuntu 5 times (16.04, 19.04).  I tried different libraries from different repos, tried to build some of the libraries, followed some tips from your readme, tried to compile different versions of the application, tried different versions of g++.  And so far it has not worked.  All the time during compilation there are some errors.  And I thought, maybe you can help? I don't know what information would be useful. Here are my last try logs. it seems like when installing with different source data (different libraries, compilers, etc.) errors occur in different places.  But once it compiled fine and worked for quite some time!

 Comment 0: > that a second instance of the server is running
if there were no `mega-cmd-server` process running, that could have been because there was a `~/.megaCmd/lockMCMD` when it shouldn't be there. starting mega-cmd-server with `--skip-lock-check` would allow startup of the server in that case.
Regarding your compilation issues, there seems to be an issue linking cryptopp when building an example application, try passing `--disable-examples`  to your configure line. Also `--disable-silent-rules` will give you some idea of what are the exact building commands. You might also need to build cryptopp yourself and pass it to MEGAcmd with `--with-cryptopp=/path/to/inst/installation`
 Comment 1: Well, to know this before)

I remember that at the time when everything worked for me, I compiled cryptopp from the sources.  I'll try your advices, hope it works.

By the way, maybe there is a way to compile your application in termux?  So far, I have not been able to find freeimage libraries for it. Can we void this troubles somehow?
