How to build Imgui example? #64

DmitriySalnikov · 2019-07-30T19:45:46Z

I have no problems with compiling MagnumIntegration::ImGui but Imgui example can't builded.
All packages installed via vcpkg.

Hi,

thank you for the very detailed report. For the second case the project is missing a copy of the FindImGui.cmake module, which is here, together witht that you'll need also

set(CMAKE_MODULE_PATH "${PROJECT_SOURCE_DIR}/modules/" ${CMAKE_MODULE_PATH})

set in CMake (assuming the FindImGui.cmake module is put in the modules/ subdirectory). You did this most probably for FindSDL2.cmake already. After you do that ... you'll most definitely end up at the first problem 😅

For the first problem -- it looks like there's some clash of targets. Since it worked when building the integration library itself (which depends on imgui from vcpkg), I don't think it's due to vcpkg being broken -- but somehow the imguiConfig.cmake the imgui vcpkg package installs doesn't get executed properly, failing to create the imgui::imgui target. Can you search your system for files named imguiConfig.cmake? Maybe there's some other one which somehow takes a priority and is causing things to break?

@Squareys, any chance you ever encountered this issue?

i have only that imguiConfig.cmake in "installed" and "packages" folders

These file pairs are identical (that's all I found):

Here is another person with the same problem: microsoft/vcpkg#5911

DmitriySalnikov · 2019-07-30T22:53:05Z

I found solution.
Just install all packages without '-static' suffix in triplets (x64-windows instead x64-windows-static).

but my test project still dont works.

The linked problem is different from what you are encountering here and the solution to that one is identical to what I said above.

Just install all packages without '-static' suffix in triplets (x64-windows instead x64-windows-static).

Glad to hear there's some solution :) Interesting -- can you check how the imguiConfig.cmake files look in this case? Is there any difference? Ideally put one here again.

but my test project still dont works.

Is it still complaining about Target "SimpleGame" links to target "ImGui::ImGui" but the target was not found or is it something different now? Did you set up the module folder and put the FindImGui.cmake file there like I said above?

I think this file has not changed.

You're right, thank you. I have not copied the modules to my project.

set in CMake (assuming the FindImGui.cmake module is put in the modules/ subdirectory). You did this most probably for FindSDL2.cmake already. After you do that ... you'll most definitely end up at the first problem 😅

But I didn't understand this message then because I didn't copy 'FindSDL2'.cmake' and didn't see any problems with SDL2. And still don't know why reinstalling all packages without '-static' helped build the examples.
I was too sleepy to read this https://doc.magnum.graphics/magnum/getting-started.html#getting-started-review 😅
Sorry for such a stupid question 😓
In the future, I will read the documentation more carefully.
Thank You

No worries, you're not the first one getting stuck on this ;)

I updated the ImGuiIntegration docs to hopefully make this requirement clearer (mosra/magnum-integration@221030a).

mosra added this to the 2019.0b milestone Jul 30, 2019
