 If you've cloned the Git repository, you will also need these tools to compile:
 
-* CMake >= 2.6      http://www.cmake.org/
-* GNU gettext       http://www.gnu.org/software/gettext/
-* CVS               http://www.nongnu.org/cvs/ (needed to run autopoint)
+* CMake >= 3.8      https://cmake.org/
+* GNU gettext       https://www.gnu.org/software/gettext/
 
 On some machines, it's been reported that this package is also needed. However,
 you might not need it:
 
-* GNU libtool       http://www.gnu.org/software/libtool/
+* GNU libtool       https://www.gnu.org/software/libtool/
 
 Installing these dependencies is distributions-specific, and we'll leave it to
 you to figure this out.
