Hello: I am trying to install iq-tree/2.3.2 on X86_64 (RHEL8) with gcc/12.2.0 openmpi/4.1.5. I have compilation error
/dist/apps/iq-tree/2.3.2/model/modelmarkov.cpp:26:10: fatal error: Eigen/EigenSolver: No such file or directory
26 | #include <Eigen/EigenSolver>

I have eigen3/3.4.0 installed. I have specified -DEIGEN3_INCLUDE_DIR=xxx/xxx.eigen3/3.4.0 (where xxx/xxx are system-dependent paths). I do not have any file named EigenSolver. However, I see EigenSolver.h in /xxx/xxx/eigen3/3.4.0/Eigen/src/Eigenvalues.

Shouldn't this be changed?

Thanks, Ajith
