installation problem on debian 9 "Configuring incomplete, errors occurred" "No CMAKE_CXX_COMPILER"

[childeofentropy]

After installing all the python dependencies mentioned in the wiki section, I do
git clone https://github.com/nvbn/everpad.git cd everpad python setup.py install

and after that this is what I get:

running install

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.

I guess the problem is in the last part were it says "configuring incomplete" about "No CMAKE_CXX_COMPILER could be found.", but I do not understand what should I do.

Thank you for your time.

update: While installing on debian 9 I have done all the steps needed, even the optional, but after
$ python setup.py install
I get the same error:

CMake Error at CMakeLists.txt:2 (project): No CMAKE_CXX_COMPILER could be found.

sudo apt-get update && sudo apt-get install build-essential
should fix your issue

it did install, and it took more than 5 minutes...wow
now it won't launch. i type 'everpad' and there is nothing there, on the start menu there is only the option 'run everpad' which leads to nothing, at least i know installation was ok
launching 'everpad' while on root terminal gives some code sequence i didn't keep track.
tried to uninstall, don't know how, just deleted the files and now running 'everpad' on terminal will give this:
