## Misc Notes
### Force NVIDIA Usage
Force the system to try to use the NVIDIA GPU. This is very useful when using a system with multiple GPUs.
```bash
__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia program arguments
```
### Mesa
```bash
MESA_DEBUG=1
MESA_GLSL=source
MESA_SHADER_DUMP_PATH=dump
INTEL_DEBUG=perf
```
### Export Build to Target Directory
Build Asset File
```bash
tar
```
Setup Build.
```bash
cmake .. -DCMAKE_INSTALL_PREFIX=/target -DCMAKE_BUILD_TYPE=Release
```
Install
```bash
cmake --build . --parallel $(nproc --all) --target install ;
```
