A blank project example showing how to use libigl and cmake. Feel free and encouraged to copy or fork this project as a way of starting a new personal project using libigl.
Then build, run and understand the libigl tutorial.
The only dependencies are STL, Eigen, libigl and the dependencies
of the igl::opengl::glfw::Viewer (OpenGL, glad and GLFW).
The CMake build system will automatically download libigl and its dependencies using
CMake FetchContent,
thus requiring no setup on your part.
Also need
sudo apt install xorg-dev
To use a local copy of libigl rather than downloading the repository via FetchContent, you can use
the CMake cache variable FETCHCONTENT_SOURCE_DIR_LIBIGL when configuring your CMake project for
the first time:
cmake -DFETCHCONTENT_SOURCE_DIR_LIBIGL=<path-to-libigl> ..
When changing this value, do not forget to clear your CMakeCache.txt, or to update the cache variable
via cmake-gui or ccmake.
Compile this project using the standard cmake routine:
mkdir build
cd build
cmake ..
make
This should find and build the dependencies and create a example binary.
From within the build directory just issue:
./example
A glfw app should launch displaying a 3D cube.
