* C++-11 compiler
## How to build
```
$ premak5 gmake
```
## Compile options
* zstd compressed .obj support. `--with-zstd` premake option.
* gzip compressed .obj support. `--with-zlib` premake option.
## Notes on AMD GPU + Linux
You may need to link with libdrm(`-ldrm`).
## Licenses
* lfpAlloc : MIT license.
