No CMAKE_CXX_COMPILER could be found.

[code-IM-perfect]

I am trying to rlottie with cmake but when I configure cmake by cmake .. in the build directory I get this-

-- The C compiler identification is GNU 9.3.0
-- The CXX compiler identification is unknown
-- The ASM compiler identification is GNU
-- Found assembler: /usr/bin/cc
-- Check for working C compiler: /usr/bin/cc
-- Check for working C compiler: /usr/bin/cc -- works
-- Detecting C compiler ABI info
-- Detecting C compiler ABI info - done
-- Detecting C compile features
-- Detecting C compile features - done
CMake Error at CMakeLists.txt:4 (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.

The error means you have no installed a C++ compiler. Make sure one of the following commands `c++`, `g++`, or `clang++` works. You did not tell us but it seems you use Windows and WSL. Try to install the compiler with the command: sudo apt-get install g++
