This seems more a cmake problem rather than a ceres solver problem.

Closing because this does not look like a ceres solver issue. Please feel free to reopen if you think this is a problem with out cmake files.

@sergiud can you take a look please.

I am happy to provide whatever details/logs from my mac you would like, say the word.

I looked at the link script being used and here is one instance of it and there are duplicates here ``` /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/c++ -Wmissing-declarations -Wno-unknown-pragmas -Wno-sign-compare -Wno-unused-parameter -Wno-missing-field-initializers -Qunused-arguments -mllvm -inline-threshold=600...

here is what cmake output looks like when I configure ``` [alpha] cmake-build: cmake ../ -- The C compiler identification is AppleClang 15.0.0.15000040 -- The CXX compiler identification is AppleClang...

@sergiud thoughts?

So this seems to be an issue with the new linker that ships with XCode 15. https://developer.apple.com/forums/thread/737707 https://github.com/orgs/Homebrew/discussions/4794

Thanks @manevalex I will take a look.

What does it mean for r11, r12, r21, r22 to conform to a rotation matrix?
