irrlicht | Minetest 's fork of Irrlicht | Game Engine library

I am trying to pass a variable to a cmake script but it I am obviously not doing it correctly. I am trying to build a chrono project by following the tutorial. Tutorial I am following is here:

https://api.projectchrono.org/tutorial_install_project.html

the CMakeLists.txt is modified below to:

I am building an application which uses tinyxml2 and few other dependencies (namely Irrlicht and IrrKlang) that I provide as .zip files in the Dependency subdirectory of my project:

I am trying to build a cross platform school project in C++ with CMake. My project requires the use of the Irrlicht library and must compile under Linux and Windows 10.

The project source path contains a lib folder, containing the Irrlicht header (in an include subfolder), an Irrlicht.dll, an Irrlicht.lib and a FindIrrlicht.cmake module.

I set CMAKE_MODULE_PATH to point to this directory, then call find_package(Irrlicht REQUIRED) in my CMakeLists.txt.

When I try to compile under Linux, everything works fine. However, when I try to run the configuration with CMake (using the CMake GUI) under Windows, the FindIrrlicht.cmake module that I have does not work (it should, since it is provided by the school and they say it should, also I know other people had it work without modifications). I believe that I have identified the cause of the problem, but I do not understance why it occurs nor how to fix it.

FindIrrlicht.cmake looks for the include directory and the Irrlicht.lib (or libIrrlicht.so under Linux, using prefix/suffix options) in some standard Linux include/library path AND under CMAKE_MODULE_PATH. When compiling on Windows, it should find everything in CMAKE_MODULE_PATH. It calls find_library like this:
