Headers not included post-build

[ba-ab-not-a-ba]

I am trying to build ASL from source on Windows 11 Enterprise. I think I succeeded, but I am surprised that only got three header files in the include directory. My question is about how I get those additional header files as a build output. I assume that I need additional header files, because when I tried to build pynumero and link it to ASL, it complained about a missing "asl_pfgh.h"...

What I did: I cloned this repository, created a build directory, ran cmake (version 4.1.0 installed via pip) and then built ASL:

git clone --recursive https://github.com/ampl/asl.git
cd asl
mkdir build
cd build
cmake .. -G "Visual Studio 17 2022" -A x64 -DCMAKE_BUILD_TYPE="Release"
& "C:\Program Files (x86)\Microsoft Visual Studio\2022\BuildTools\MSBuild\Current\Bin\MSBuild.exe" ".\ASL.sln" /p:Configuration=Release /p:Platform=x64 /t:Build

Build succeeded. But when I look inside the generated include folder:

cd include
ls

Directory: C:\Projects\asl\build\include

Only three files... I thought this was fine, until I tried to build pynumero and link it to ASL which complained about a missing "asl_pfgh.h".

Where are the header files supposed to go and how can I get them from the build? Sorry if this not an ASL problem. Giving up for the weekend and thought it was worth asking.
