 ** compiler
-By default I use clang, if you want to use gcc just
-edit the =CMakeLists.txt= file and change =clang= to =gcc=
+#+BEGIN_SRC sh
+  > export CC=clang
+  # or
+  > export CC=gcc
+#+END_SRC
 
 ** make
 #+BEGIN_SRC sh
-# clone the repo
-> cd ~/code; git clone https://gitlab.com/grm-grm/ck
-# make a build directory and enter it
-> mkdir ~/ck_build; cd ~/ck_build;
-# run cmake
-> cmake ~/code/ck

 * for devs
-** make
+** CMake options
+cmake accepts the following options:
+#+BEGIN_SRC cmake
+  option(CK_ASAN "Build with asan")
+  option(CK_DEBUG "Build with debug symbols")
+  option(CK_TESTS "Make the tests")
+  option(CK_SHARED "Build with shared lib")
+#+END_SRC
+
+To use any one of them append it after the cmake command like so:
+#+BEGIN_SRC sh
+  cmake -DCK_ASAN=1 -DCK_DEBUG=1 -DCK_TESTS=1 ~/code/ck
+#+END_SRC
+
 Just build with address sanitizer enabled like so:
 llvm has better asan than gcc, so I use that.
