Fork Lean on github : https://github.com/leanprover/lean2

Create a projects directory

cd ~
mkdir projects
cd projects

Clone your fork

git clone https://github.com/[your-user-name]/lean2.git

Build Lean in release mode

cd lean2
mkdir -p build
cd build
cmake -D CMAKE_BUILD_TYPE=Release ../src
make

Alternative ways to build

Using Ninja (to speed up build)

cmake -DCMAKE_BUILD_TYPE=RELEASE -G Ninja ../src
ninja

Using Boost (to speed up build)

cmake -D CMAKE_BUILD_TYPE=Release -D BOOST=ON ../src
make

Build in debug mode

cmake -DCMAKE_BUILD_TYPE=DEBUG ../src

You need to also set up the Emacs Mode.
