Build instructions for new CppAD-codegen

[ckurtz22]

There is a lack of build instructions or process for the new CppAD-codegen branch (or docs in general for that matter :P ).
I've managed to fumble most of the way so far on my own to get a "successful" build but now getting runtime errors when I run the main executable MPCC. Also, not sure if I need to build the contents of the ADCodeGen folder or not, but cannot seem to get this folder to build.

Sorry I know, I will add instructions and plan to add a docker container:

These instructions are not tested, but is what I remember plus some old personal documentation

Installation:

Compared to the instructions for the other branches:
build blasfeo and hpipm into root with cmake following their changed instructions

CppAD:

Download CppAD
cd in folder
mkdir build
cd build
cmake ..
sudo make install

I think you can also use sudo apt install cppad

CppAD CodeGen

git clone https://github.com/joaoleal/CppADCodeGen.git CppADCodeGen
cd in folder
mkdir build
cd build
cmake ..
sudo make install

Build:

Build CppAD Libs:

cd ADCodeGen
mkdir build
cd build
cmake ..
make
./ADCodeGen

Build MPCC:

mkdir build
cd build
cmake ..
make
./MPCC

Great, thank you!

Well my issue turned out to be silly anyways, I was building from the C++ dir like the other branches instead of C++/build :)

#84 kinda fixes this as it adds the steps needed to the install script

Thanks for updating the install instructions. I will test everything as soon as I have time and approve the merge requests.
