I'm on Ubuntu 16.04. I installed cmake with the command

sudo apt install cmake

It installed cmake 3.5.1. Now I want to use cmake 3.7 - I downloaded an archive with binaries (i.e cmake-3.7.0-Linux-x86_64.tar.gz) and extracted it, but how do I run it using the cmake command? My current attempt to run

cmake --version

returns the "old" 3.5.1 version.

Remove old version using:

apt-get purge cmake

You can use new version of cmake by adding its bin directory path to $PATH. An alternative solution is to extract tar.gz package and go to the directory made after extracting and run following commands:

cp -r bin /usr/
cp -r doc /usr/share/
cp -r man /usr/share/
cp -r share /usr/

The second method is the same as installation process which .deb package does!

  • With the difference that you can remove a deb package easily. How do you plan to remove this when not needed? – muru Nov 19 '16 at 13:46
  • I agree - how to remove it if we just copied folders? – nikitablack Nov 19 '16 at 15:07
  • @muru: It is drawback of installing a package using this method. Compiling from source code has the same problem in some packages! In this case this package could be removed by deleting any file which is copied. Another solution is to make a .deb package and installing it. – SuB Nov 19 '16 at 15:45
  • There is a package for cmake 3.7 here in Ubuntu repository for zesty version, but i recommend you not using this package. Installing this package need to force dpkg to ignore package version check and may cause broken package database. – SuB Nov 19 '16 at 16:28
