This extension of the libigl example
project demonstrates how to
set up a CMake project using libigl that has multiple executables linked to the
same project-specific "core" functionality (in this case the function func
which prints hello).
mkdir build
cmake ../
make
will build libcore.* library (containing the compiled func) and example1 and
example2 executables.
Changing the implementation inside func.cpp and then reissuing
make
will recompile and link libcore.*, but only re-link example1 and example2.
Changing the implementation inside example1.cpp and example2.cpp and then
issuing:
make example2
Will only recompile and relink example2.
