There was an error with include <webkit2/webkit2.h>
sudo apt-get install libwebkit2gtk-4.0-dev
There was an error with include <enchant.h>
sudo apt-get install python-enchant libgtk-3-dev
#maybe-not 2nd one. Sorry unsure! as I tried so many installs to fix..!
There was an error with #include <vte/vte.h>
sudo apt install libvte-dev
There was an error with #include <gpgme.h>
sudo apt install libgpgme-dev
There was an error with #include <git2.h>
sudo apt install libgit2-dev
sudo apt-get install -y libvte-2.91-0 valac #mutiterm
./configure
make
sudo make install
