Instructions for GitHub users
The current recommended way of installing oac-tree GUI is by compiling it from the source as a part of oac-tree bundle:
git clone --recurse-submodules https://github.com/oac-tree/oac-tree-bundle.git
mkdir <BUILD_DIR>
cd <BUILD_DIR>
cmake -DCMAKE_INSTALL_PREFIX=<INSTALL_PREFIX> <SOURCE_DIR>
make -j24
# note that install step is intentionally skipped
source <INSTALL_PREFIX>/bin/oac-tree-path.sh
Please see detailed oac-tree bundle installation instructions
