In static builds find_package(Eigen3) is skipped, leaving Eigen3::Eigen undefined when admesh and clipper try to link against it. Add an unconditional find_package(Eigen3 CONFIG QUIET) guard in the main CMakeLists before add_subdirectory(deps_src). deps_src/eigen now simply provides the unnamespaced alias and fatals clearly if the target is missing.
Eigen is a C++ template library for linear algebra: matrices, vectors, numerical solvers, and related algorithms.
