How to use Zep with Mahi Gui?

[traverseda]

I'm trying to integrate Zep with Mahi-Gui, but unfortunately I'm too inexperienced with cmake to figure out how to do it.

Any tips? Here's what I have so far

include(FetchContent) 
FetchContent_Declare(mahi-gui GIT_REPOSITORY https://github.com/mahilab/mahi-gui.git) 
FetchContent_MakeAvailable(mahi-gui)

FetchContent_Declare(Zep GIT_REPOSITORY https://github.com/Rezonality/zep.git)
FetchContent_MakeAvailable(Zep)
project(catCad)
add_subdirectory(src)

add_executable(catCad "src/main.cpp")
target_link_libraries(catCad mahi::gui Zep::Zep)

My output is

`CMake Error at _deps/zep-src/extensions/CMakeLists.txt:10 (find_package):
  By not providing "Findimgui.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "imgui", but
  CMake did not find one.

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

    imguiConfig.cmake
    imgui-config.cmake

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

Not sure how to approach this.

I'm afraid I'm not around for a few hours, but my first reaction here is that you need to set options to just get the library, when calling CMake:
-DBUILD_EXTENSIONS=OFF -DBUILD_DEMOS=OFF -DBUILD_TESTS=OFF
Since I think you just want the library here. I think the Extensions require ImGui, and you don't have that installed as a package on your system. Since Mahi gui (which coincidentally I spotted today!) already includes ImGui, you might need to wrangle the code a bit.
I can probably have a look at how to make this work for you at some point this week.

Thanks, I'm not in any hurry this is just me playing around with CPP, not a serious project. I would definitely appreciate the Mahi-Gui support though, and I imagine others would as well.

I guess I never got around to this one. If anyone does this, do let me know. The integration example for Zep should now help....
