Description

Previously the cmake generator provided a imgui_RES_DIRS variable pointing to the res/ folder under the package installation, which was the only way of obtaining the packaged bindings which are located at res/bindings/.

Steps to reproduce

create a CMakeLists.txt which depends on one of the packaged bindings, using the cmake and cmake_find_package

find_package(SDL2 REQUIRED)
find_package(imgui REQUIRED)

add_library(imgui_impl_sdl OBJECT ${imgui_RES_DIRS}/bindings/imgui_impl_sdl.cpp)
target_include_directories(imgui_impl_sdl PUBLIC ${imgui_RES_DIRS}/bindings/)
target_link_libraries(imgui_impl_sdl PUBLIC imgui::imgui PRIVATE SDL2::SDL2)

add_executable(main)
target_link_libraries(main PRIVATE main)
