cmake fails for me

[bfrk]

This is what cmake gives me, I don't know much about cmake so perhaps this is a trivial problem?

CMake Error at CMakeLists.txt:77 (find_package):
  By not providing "FindROOT.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "ROOT", but
  CMake did not find one.

  Could not find a package configuration file provided by "ROOT" with any of
  the following names:

    ROOTConfig.cmake
    root-config.cmake

  Add the installation prefix of "ROOT" to CMAKE_PREFIX_PATH or set
  "ROOT_DIR" to a directory containing one of the above files.  If "ROOT"
  provides a separate development package or SDK, be sure it has been
  installed.

I was playing around with ROOT but I just removed it. Does it work now?

[bfrk]

The ROOT related error is gone but I still have difficulties. It now says

CMake Error at src/epics/CMakeLists.txt:32 (target_compile_features):
  target_compile_features specified unknown feature "cxx_std_17" for target
  "epics".

I guess my system is too old and the compiler does not yet support C++17. Are you sure you need it? (Dear Imgui says it doesn't even need C++11.)

[bfrk]

I have removed cxx_std_17 in src/epics/CMakeLists.txt and src/gui/CMakeLists.txt and now cmake completes successfully. Now when I do make I get

[ 17%] Building CXX object src/3rd_party/CMakeFiles/ImGui.dir/imgui/imgui_impl_glfw_gl3.cpp.o

 #include <GLFW/glfw3.h>

It seems that glfw3, too, is not supported in my distribution: libglfw2 and libglfw-dev are the only packages offered. I'll try on another machine now.
