Installation

Your about to spend some times to install it /)

Install TIXI

Make sure that tixi is compatible with the "fPIC" compiler option. (You can add set(CMAKE_POSITION_INDEPENDENT_CODE ON) to the CMakeList.txt of TIXI)
Then, build tixi:
mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX=install ..
make
make install

Then you can copy the file generated by make install into your local system library.
eg:
cp -rf install/* /usr/local/

Create internal python wrapper

For the moment, there are some tricks to build the python python api. Especially because the pythonOCC core is hard to set correctly.

1. Install anaconda
2. Install tigl3 in anaconda
   conda install tigl3 -c dlr-sc
3. Add the path of pythonocc-core of this anaconda env to the cmake path.
   eg: edit the FindPythonOCC.cmake file has follow:
   FIND_PATH(PythonOCC_SOURCE_DIR NAMES src/SWIG_files/wrapper/Standard.i PATHS /opt/anaconda3/envs/tigl/src/pythonocc-core/
4. Set the tixi used to build to be the tixi used by the anaconda env.
   eg (replace the tixi search in the CMake main file ) :
   FIND_PATH(TIXI_PATH NAMES "tixi3-config.cmake" PATHS "/opt/anaconda3/envs/tixi/lib/tixi3/" )
find_package( tixi3 3.0.3 REQUIRED CONFIG PATHS "${TIXI_PATH}" NO_DEFAULT_PATH )
5. Set the cmake option: TIGL_BINDINGS_PYTHON_INTERNAL=ON
6. Create a new conda env with the same parameters has the one containing the pythonocc-core library
7. Copy all the file of the build to the new conda env. For exemple, this script try to do this:
   #! /bin/bash
BUILD_DIR="path_to_build"
CONDA_DIR="path_to_env"
echo "We will try to move the build internal tigl python api to conda env "
cp $BUILD_DIR/bindings/python_internal/*.py $CONDA_DIR/lib/python3.6/site-packages/tigl3/
cp $BUILD_DIR/bindings/python_internal/*.so $CONDA_DIR/lib/python3.6/site-packages/tigl3/
cp $BUILD_DIR/lib/* $CONDA_DIR/lib

Install for Archlinux

Install oce 17.2 and patch it.

1. Download the source https://github.com/tpaviot/oce/releases/tag/OCE-0.17.2
2. Patch it with https://github.com/DLR-SC/tigl/blob/cpacs_3/patches/oce-0.17/fix-geomapi_extremacurvecurve.patch
3. Build the library with the following options (default ones):
   cmake -DOCE_BUILD_SHARED_LIB=ON \
