You need 2 components :
- the library itself, correctly installed (.h files in /usr/include, .so 
files in /usr/lib...) Under Linux, the package manager automatically takes 
care of this : "apt-get install ..."
- the corresponding .vapi file in /usr/share/vala/vapi/.

apt-get install libgee-dev 

It already includes the .vapi.

Under Win32 with MinGW, You install the library using the MinGW package 
manager, and put the .vapi in C:\ProgramData\vala-<version>\vapi. 

Specific here. MinGW doesn't provide GTK+3 for now. But you'll find it by 
typing "gtk+3 win32" in Google.
