For building ccextractor using cmake folllow below steps.. Step 1) Check you have right version of cmake installed. ( version >= 3.0.2 ) We are using CMP0037 policy of cmake which was introduced in 3.0.0 since we have tested our system only with cmake version 3.0.2, I would suggest to use 3.0.2 or higher version. Step 2) create a seprate directory where you want to build the target. In Unix you can do it using follwing commands. ~> cd ccextractor ~> mkdir build Step 3) make the build sytem using cmake ~> cmake ../src/ Step 4) Compile the code. ~> make ~> make install Step 5) Use CCextractor as you would like
