[devil] build failure

[chaquator]

Host Environment

• OS: Windows 10 x64
• Compiler: gcc 10.2.0 mingw64

To Reproduce
Steps to reproduce the behavior:

1. ./vcpkg install devil
2. Try to build a project with ILUT
   Somewhere in the C file:

#include <IL/il.h>
#include <IL/ilut.h>

Somewhere in the CMake file:

find_package(DevIL REQUIRED)
target_link_libraries(main PRIVATE ${IL_LIBRARIES} PRIVATE ${ILUT_LIBRARIES})

Failure logs

PS S:\c\C\compute_test\build> make

Additional context
This issue goes away when I copy ilut_config.h from DevIL/include/IL into vcpkg/installed/x64-windows/include/IL.
It seems like upon installing DevIL, this file fails to be copied.

@chaquator, thanks for reporting this issue!

It looks the headers hasn't been installed, see https://github.com/DentonW/DevIL/blob/master/DevIL/src-ILUT/CMakeLists.txt#L102, could you also report an issue to Upstream?

@chaquator, I have submitted a PR to fix this, btw, I have already report this issue to Upstream DentonW/DevIL#96

Awesome, thank you so much!
