Building from source

[amuuza]

Hi, congratulations for such a nice program. It is great, I saw it working and loved it.

But now I would like to run int on a Trisquel 8 machine (it is based on Ubuntu Xenial) building it from source, I do not want to install it through a package or repo.

I have tried, but I get this problem:

amuuza@trisquel8:~/git/timeshift$ make all
cd src; make all
make[1]: Entering directory '/home/amuuza/git/timeshift/src'
Package vte-2.91 was not found in the pkg-config search path.
Perhaps you should add the directory containing `vte-2.91.pc'
to the PKG_CONFIG_PATH environment variable
No package 'vte-2.91' found
/bin/bash: line 0: test: -lt: unary operator expected
Package gtk+-3.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `gtk+-3.0.pc'

Could anyone please help me?
Or maybe let me know where I could ask for help...

Thank you!
