Wrong compiler standard in CMakeLists.txt

[adryan1994]

System information (version)

• Sophus => 1.22.10
• Operating System / Platform => Linux / Ubuntu 22.04 LTS
• Compiler => gcc 11.3.0

Multiple errors occurring during installation process because of C++14 compiler standard instead of C++17 in CMakeLists.txt file:

/usr/local/include/ceres/product_manifold.h:274:36: note: ‘std::void_t’ is only available from C++17 onwards

Solution:

• Change line 27 to set(CMAKE_CXX_STANDARD 17)
• Change line 37 to SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wall -Werror -Wextra -std=c++17-Wno-deprecated-declarations -ftemplate-backtrace-limit=0")

Steps to Reproduce

1. git clone https://github.com/strasdat/Sophus.git
2. cd Sophus && mkdir build && cd build
3. cmake ..
4. make

Expected behavior Successful installation

Hi, I am facing the same issue and managed to compile the project with your suggestion. I think it would be great if you can open an PR for this issue.
