  --- BEGIN ISSUE ---
  [package] imgui/1.84.1: Shared library does not automatically import global data symbols
  ### Package and Environment Details (include every applicable attribute)
    * Package Name/Version: **imgui/1.84.1**
    * Operating System+version: **Windows 10 21H1 Build 19043.1165**
    * Compiler+version: **Visual Studio 16 (2019)**
    * Docker image: **N/A**
    * Conan version: **conan 1.39.0**
    * Python version: **Python 3.9.6**
  
  
  ### Conan profile (output of `conan profile show default` or `conan profile show <profile>` if custom profile is in use)
  ```
  [settings]
  os=Windows
  os_build=Windows
  arch=x86_64
  arch_build=x86_64
  compiler=Visual Studio
  compiler.version=16
  build_type=Release
  [options]
  [conf]
  [build_requires]
  [env]
  ```
  
  
  ### Steps to reproduce (Include if Applicable)
  Try to reference any code that uses global data symbols since those need to use `__declspec(dllimport)` when using [`WINDOWS_EXPORT_ALL_SYMBOLS`](https://cmake.org/cmake/help/latest/prop_tgt/WINDOWS_EXPORT_ALL_SYMBOLS.html#windows-export-all-symbols). One example could be using [`ImGuiTextBuffer`](https://github.com/ocornut/imgui/blob/v1.84.1/imgui.h#L2078) (which has `IMGUI_API static char EmptyString[1];`).
  The following diff is for ImGui's [`test_package.cpp`](https://github.com/conan-io/conan-center-index/blob/master/recipes/imgui/all/test_package/test_package.cpp) and can reproduce this issue.

  Then, try to create the package with `conan create . imgui/1.84.1@ -o imgui:shared=True`.

  ```
  
  </details>
  
  I think the simplest solution would be to add something like this
  
  ```
  if self.options.shared and self.settings.os == "Windows":
      self.cpp_info.defines.append("IMGUI_API=__declspec(dllimport)")
  ```
  
  I'd be happy to open a PR with this change.
