deleting this line:
#define YT_DISCARD_HTTPS
and compiling worked! Thanks.
I followed these instructions:

'How to compile in Debian Linux' instructions could be added to Readme.txt:
install subversion and build tools so you can get, and compile, current sourcecode:
sudo apt-get install subversion libqt4-dev-bin libqtwebkit-dev build-dep build-essential
get the sourcecode:
cd ~
svn co https://subversion.assembla.com/svn/smp ... ube/trunk/ smtube
build the deb file:
cd ~/smtube/
./create_deb.sh
install the deb file:
cd ../
sudo dpkg -i smtube_[current version].deb
