Hello,
I used the following steps to build the example `raylib-d` program.
(https://github.com/schveiguy/raylib-d#example)
### Install Raylib (Ubuntu/Debian)
1. `sudo apt install libasound2-dev mesa-common-dev libx11-dev
libxrandr-dev libxi-dev xorg-dev libgl1-mesa-dev libglu1-mesa-dev`
1. `cd /tmp`
1. `git clone https://github.com/raysan5/raylib.git raylib`
1. `cd raylib`
1. `mkdir build && cd build`
1. `cmake -DBUILD_SHARED_LIBS=ON ..`
1. `make -j2`
1. `sudo make install`
1. `sudo reboot now`
### Dlang Raylib API
1. Install Dlang
1. Navigate to project root directory
1. `mkdir source`
1. `touch source/app.d`
1. Code: https://github.com/schveiguy/raylib-d#example
1. `dub add raylib-d`
1. `dub build`
### Errors encountered

### Questions
There appears to be a linker problem with regards to missing symbols,
but normally I would expect `make install` to place the shared libs in
their proper places.
You built the unreleased version of raylib, where they changed the name
of that symbol. (see
https://github.com/raysan5/raylib/commit/082920eb800d7d7612d500a4bbc46b21ff232424)
Try `git checkout 4.2.0` on the raylib library before building, or use
the released binary.
raylib is notorious for making breaking changes. On the next release, I
will have to update that symbol name.
