I've tried on my windows PC and in wsl, but it doesn't work, and I'm using the Doxyfile.in it gives in eigen-3.4.0\doc
error: tag HTML_HEADER: header file '${Eigen_BINARY_DIR}/doc/eigendoxy_header.html' does not exist
It seems that it can't understand the Eigen_BINARY_DIR or something like that. Does it related to my OS? Do I need to try it in macOS?
I know where I'm wrong, I didn't process the file before using Doxygen, so I was confused by the difference between Doxyfile and Doxyfile.in and think it may related to my OS.
I tried to use CMake but there is still a problem...
I went to Eigen website and try to learn how to use CMake, I try cmake . in WSL(in eigen-3.4.0/doc) but it reports an error, which said:
CMake Error at CMakeLists.txt:14 (check_cxx_compiler_flag):
Unknown CMake command "check_cxx_compiler_flag".
-- Configuring incomplete, errors occurred!
