Debian 12 build failed: please set STRATAGUS_INCLUDE_DIR and STRATAGUS

[egberts]

Describe the bug

During cmake, I get the following error:

Could not find stratagus, please set STRATAGUS_INCLUDE_DIR and STRATAGUS
-- Configuring incomplete, errors occurred!

To Reproduce
Steps to reproduce the behavior:

Using latest main branch of Wargus/wargus (7763ac2)

Cloned onto my Debian 12 (Bookworm), I get the following error:

$ git clone https://github.com/Wargus/wargus
$ cd wargus
$ mkdir build
$ cd build
$ cmake .. && make

CMake Error at cmake/modules/FindStratagus.cmake:24 (message):
  Could not find stratagus, please set STRATAGUS_INCLUDE_DIR and STRATAGUS
Call Stack (most recent call first):
  CMakeLists.txt:109 (find_package)

Expected behavior
I expect some kind of documentation to show how to tie this Stratagem into Wargus. Maybe something like a more expansive environment variable definition as to what the following should point to:

• STRATAGUS - points to the binary file, the root directory of stratagus local repo, build area of stratagus?
• STRATAGUS_INCLUDE_DIR - points to the /usr/include/stratagus (after installing stratagus), points somewherer inside the local stratagus repo

Desktop (please complete the following information):

• OS: Debian 12, no patches

I get the same thing, freshly cloned. I tried setting env variables mentioned in the error but it seemed to ignore them.
