With any luck, you're using a modern, package-based operating system
that has all of these packages available in the distribution. In that
case a simple command will install everything you need. For example:
On Debian and similar systems:
- sudo apt-get install libxapian-dev libgmime-2.4-dev libtalloc-dev
+ sudo apt-get install libxapian-dev libgmime-2.6-dev libtalloc-dev
Or on Fedora and similar systems:
