How can I install Extra CMake Modules on Ubuntu 14.04 (Trusty)

Edit (Brought to top)

git clone git://anongit.kde.org/extra-cmake-modules
cd extra-cmake-modules
mkdir build
cd build
cmake .. # or run : cmake -DCMAKE_INSTALL_PREFIX=/usr .. &&
make
sudo make install

You can install the latest qt version as follows:

wget http://download.qt.io/official_releases/qt/5.7/5.7.0/qt-opensource-linux-x64-5.7.0.run
chmod +x qt-opensource-linux-x64-5.7.0.run
./qt-opensource-linux-x64-5.7.0.run

Original answer

The extra-cmake-modules is available on Ubuntu 16.04 , 16.10 and 17.04 version.

No summary available for extra-cmake-modules in ubuntu utopic.

You can install it on Ubuntu 14.04 but it is not recommended , it can break your System.

You can edit your /etc/apt/sources.list then add the following line:

deb http://cz.archive.ubuntu.com/ubuntu xenial main universe

Then update your system some dependencies will be upgraded

to install it run:

sudo apt install extra-cmake-modules
