Cmake . issues

[DarthCaesium]

When I run cmake . in the command terminal, I get this:

-- The CXX compiler identification is unknown CMake Error at CMakeLists.txt:2 (project): No CMAKE_CXX_COMPILER could be found.

Tell CMake where to find the compiler by setting either the environment variable "CXX" or the CMake cache entry CMAKE_CXX_COMPILER to the full path to the compiler, or to the compiler name if it is in the PATH.

-- Configuring incomplete, errors occurred! See also "/home/DarthCaesium/joycond/CMakeFiles/CMakeOutput.log". See also "/home/DarthCaesium/joycond/CMakeFiles/CMakeError.log".

I have already run clone git https://github.com/DanielOgorchock/joycond/, cd joycond, sudo apt install libevdev-dev and sudo apt install libudev-dev.

If it helps, I'm running Linux Mint Cinnamon 20.2.

I had this issue on Ubuntu because I was missing g++. The command on Ubuntu to install it was sudo apt-get install g++, but on Mint it could be different, so make sure you use the right one for your distro.

sudo dnf install g++ worked on Fedora

After installing g++ I seem to get the error continued:

CMakeError.log is filled with a lot of "No such file or directory" errors.
