SofaCaribou compilation on Windows

[ruiliang-gao]

I am having cmake errors trying to compile SofaCairbou on sofa v20.12 and latest Caribou source.
I added the SOFA_INSTALL environment variable as stated in the instructions.
My cmake version is 3.20.1, compiler specified for x64, VS2019.
I set "Caribou_DIR" to "CaribouSrc/caribou/src/Caribou" which is where I clone the Caribou source code.

The full Cmake output is attached below:

Hi @rgao15 ,

You don't need to set the Caribou_DIR cmake variable. Can you try the following:

1. Create a directory somewhere on your PC named sofa_plugins. Clone the source code of Caribou inside of it. For example:

$ mkdir "C:/Users/Ruiliang/Documents/sofa_plugins"
$ git clone https://github.com/jnbrunet/caribou.git "C:/Users/Ruiliang/Documents/sofa_plugins/caribou"

2. Create a C:/Users/Ruiliang/Documents/sofa_plugins/CMakeLists.txt file containing the following:

cmake_minimum_required(VERSION 3.12)

find_package(SofaFramework)
sofa_add_plugin(caribou/ SofaCaribou)

3. Go into your SOFA's build directory, and add this sofa_plugins path to the SOFA_EXTERNAL_DIRECTORIES CMake variable. Then, activate the compilation of the plugin using the CMake variable PLUGIN_SOFACARIBOU. For example:

$ cd C:/Users/Ruiliang/Documents/sofamaster/build
$ cmake -DSOFA_EXTERNAL_DIRECTORIES="C:/Users/Ruiliang/Documents/sofa_plugins" .
$ cmake -DPLUGIN_SOFACARIBOU=ON .

Finally, build SOFA. This should build the SofaCaribou plugin at the same time.
