CMake support for ImGui

ImGui has been designed to be used without CMake or any other build tool, by simply adding the ImGui source files to your project.

In case it fits your workflow better you can use ImGui just like any other CMake-enabled library. To allow for the same customization features (imconfig.h) as without CMake, ImGui will be added to your project as a set of source files and not as an actual compiled library.

The actual ImGui repository is referred as a submodule. The submodule tracks the master branch of the ImGui repo which means it's still tied to a specific commit but it's easier to update. So you can always execute:

git submodule update --remote

to get the latest commits before configuring/installing the library.

This repo contains a test script ./cmake-testbuild.sh which builds the ImGui CMake-project (this directory) then builds the OpenGL/GLFW examples in separate build trees. The script is tested on MacOSX, Linux, Windows. The ImGui library itself (which has no OpenGL and GLFW dependencies) will work on a wider range of platforms.

It also contains an additional imconfig_example which demonstrates using a custom imconfig.h.

Donating

If you're using ImGui in your projects, please consider supporting its development. For details see the README.md of the ImGui project.

Usage:

Configure and install the CMakeLists.txt in this directory to create the imgui-config.cmake config-module. Then,

with CMake version 3.3 or later:

find_package(imgui REQUIRED)
...
target_link_libraries(<my-target> ... imgui ...)

with CMake versions 2.8.12 - 3.2

find_package(imgui REQUIRED)
...
add_exutable(<my-target> ... ${IMGUI_SOURCES})
target_link_libraries(<my-target> ... imgui ...)

The first method requires the CMake target property INTERFACE_SOURCES which is implemented completely only in V3.3.

For a quick test of the CMake build and also as an example check out cmake-testbuild.sh in this directory.

Customization

To use a custom imconfig.h,

copy include/imconfig-sample.h from the install directory to your project and edit it

define IMGUI_INCLUDE_IMCONFIG_H in your project and add its path:

  target_compile_definitions(<my-target> PRIVATE IMGUI_INCLUDE_IMCONFIG_H)
  target_include_directories(<my-target> PRIVATE <path-to-imgui.h>)

Also, see ./examples/imconfig_example
