In Casino Royale, after Bond has killed Mollaka the Bomb maker at the embassy in Madagascar, M is summoned to appear in front of a committee in the Houses of Parliament. Bond's actions are questioned by the committee and they hold M responsible. M and Villiers are walking through what appears to be the Houses of Parliament after the meeting.
The scene in the film pictures the Parliament and then cuts to the Committee room where M and Villiers are walking out.
"Christ I miss the cold war!"
The library, however, is not located in London, but in a monastery in Prague. The hall where M and Villiers are walking through is called the Philosophical Hall, and can be found at the Strahov Monastery. The monastery was founded in 1143 and the Philosophical Hall dates back to the late 1700's. The entire hall was totally renovated between 2009-2010.
In the adjacent room to the Philosophical Hall, a fake wall with the committee room entrance was put up. It is quite obvious that the walls with the red wallpaper are backdrops. Especially when you look through the room in the background.

"I give Bond 00 status and he celebrates by shooting up an embassy! Is the man deranged?!"
