CGAL 6.x still unconditionally includes boost/config.hpp in its
config.h, so Boost headers are required even with CGAL_DISABLE_GMP/MPFR.
Use system Boost via find_package instead of the removed 211 MB tarball.
Tests-only mode remains completely dependency-free.
Install: brew install boost (macOS)
apt install libboost-dev (Debian/Ubuntu)

Restructures the CMake build into three clearly separated modes:
(default) tests only – Eigen + GTest, no heavy deps
-DWITH_VIEWER=ON builds viewer lib (libigl / GLFW / GLAD)
-DWITH_CGAL=ON builds conformallab_core CLI app;
implies WITH_VIEWER automatically
Changes:
- code/CMakeLists.txt: viewer and core targets are now guarded by
option() flags; GTest / tests target is always built
- code/deps/Cmakelists.txt: CGAL, libigl, glfw, glad are only
extracted when the corresponding mode is enabled; Eigen always
- Remove Boost (211 MB tarball, 0 usages in the codebase – CGAL 6.x
does not require Boost for Simple_cartesian / Surface_mesh / basic IO)
- Remove code/src/main.cpp (dead file, not referenced in CMake)
All 16 C++ tests pass in tests-only mode (verified locally).

- include/matrix_utility.hpp: 4x4 mapping matrix R·from=to (Eigen)
- include/projective_math.hpp: dehomogenize, hyperbolicDistance,
isOnSegment (collinearity + betweenness via 3D cross/dot),
getPointOnCorrespondingSegment (parameter by arc-length ratio)
- test_matrix_utility.cpp: port of MatrixUtilityTest (1 test)
- test_surface_curve_utility.cpp: port of SurfaceCurveUtilityTest
testIsBetween and testGetPointOnSegment_SegmentEdge (2 tests)
- tolerance adjusted to 1e-12 for matrix inversion (2.7e-15 rounding
from Eigen vs jReality's LU; both well within meaningful accuracy)
Total: 16/16 tests pass

- Add Google Test via CMake FetchContent (v1.14.0)
- Add clausen.hpp: Clausen integral, Lobachevsky function, Im(Li2)
- Add hyper_ideal_utility.hpp: generalized and ideal-vertex hyperbolic
tetrahedron volume formulas using Eigen for the 4x4 Gram determinant
- Port ClausenTest (5 tests) and HyperIdealUtilityTest (8 tests) from
Java/JUnit — all 13 pass with same tolerances as the Java originals
- Fix pre-existing VIEWER/viewer case mismatch in CMakeLists.txt
