CMake Error at CMakeLists.txt:57

I've got an error while I was trying to install SLiM

This is the complete message:

I don't know anything about Ubuntu, but a few days ago i was installing SLiM on Linux Mint and this wasn't a problem. I'll hope someone could help me.

Hi!  This error doesn't have anything to do with SLiM; your build is failing before it ever even looks at a SLiM source file.  It looks like Cmake is having trouble figuring out what C++ compiler you have installed (if you have one installed at all).  Section 2.4.3 of the manual has a list of common packages that can be helpful to install; I'd try installing those to see if that perhaps helps.  Perhaps "build-essential" and "cmake" are likely candidates.  Besides that, google is your friend – trying searching on something like "No CMAKE_CXX_COMPILER could be found Ubuntu" and see what you get.  Good luck!

-B.
