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.
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_bin binary.
From within the build directory just issue:
./example
A glfw app should launch displaying a 3D cube.
