# Build Instructions
## Install CMake
## Build on all platforms using vcpkg
You can download and install assimp using the [vcpkg](https://github.com/Microsoft/vcpkg/) dependency manager:
```bash
git clone https://github.com/Microsoft/vcpkg.git
cd vcpkg
./bootstrap-vcpkg.sh
./vcpkg integrate install
vcpkg install assimp
```
The assimp port in vcpkg is kept up to date by Microsoft team members and community contributors. If the version is out of date, please [create an issue or pull request](https://github.com/Microsoft/vcpkg) on the vcpkg repository.
## Manual build instructions
### Install CMake
Asset-Importer-Lib can be build for a lot of different platforms. We are using cmake to generate the build environment for these via cmake. So you have to make sure that you have a working cmake-installation on your system. You can download it at https://cmake.org/ or for linux install it via
```bash
sudo apt-get install cmake
```
## Get the source
### Get the source
Make sure you have a working git-installation. Open a command prompt and clone the Asset-Importer-Lib via:
```bash
git clone https://github.com/assimp/assimp.git

### Build instructions for Windows with Visual-Studio
First you have to install Visual-Studio on your windows-system. You can get the Community-Version for free here: https://visualstudio.microsoft.com/de/downloads/

## Build instructions for MinGW
### Build instructions for MinGW
Older versions of MinGW's compiler (e.g. 5.1.0) do not support the -mbig_obj flag
required to compile some of assimp's files, especially for debug builds.
Version 7.3.0 of g++-mingw-w64 & gcc-mingw-w64 appears to work.

Besides the toolchain, compilation should be the same as for Linux / Unix.
## CMake build options
### CMake build options
The cmake-build-environment provides options to configure the build. The following options can be used:
- **BUILD_SHARED_LIBS ( default ON )**: Generation of shared libs ( dll for windows, so for Linux ). Set this to OFF to get a static lib.
- **BUILD_FRAMEWORK ( default OFF, MacOnly)**: Build package as Mac OS X Framework bundle

- **ASSIMP_BUILD_SAMPLES ( default OFF )**: If the official samples are built as well (needs Glut).
- **ASSIMP_BUILD_TESTS ( default ON )**: If the test suite for Assimp is built in addition to the library.
- **ASSIMP_COVERALLS ( default OFF )**: Enable this to measure test coverage.
- **ASSIMP_ERROR_MAX( default OFF)**: Enable all warnings.
- **ASSIMP_WERROR( default OFF )**: Treat warnings as errors.
- **ASSIMP_ASAN ( default OFF )**: Enable AddressSanitizer.

Unfortunately aiNode has bone structures and meshes too, yet we can't assign
the mesh to a bone aiNode as a skin may refer to several aiNodes. Therefore
I've decided to import into this structure:
aiScene->mRootNode
| |->mMeshes (all the meshes)
| \->children (empty if there's no skeleton imported, no meshes)
| \->skeleton root aiNode*
| |->bone aiNode
| | \->subbone aiNode
| |->bone aiNode
| | ...
| \->bone aiNode
\->mMeshes[]
\->aiBone, referencing mesh-less aiNodes from above
* - normally one, but if a model has several skeleton roots, then all of them
are listed in aiScene->mRootNode->children, but all without meshes
