|
||||||
|
|
||||||
|
## Build
|
||||||
|
|
||||||
|
Specify these root directories for dependencies in [make.bat](make.bat) script:

||||||
|
* GLEW_ROOT
|
||||||
|
* stb_image_ROOT
|
||||||
|
* ComputeEngine_ROOT
|
||||||
|
|
||||||
|
Run [make.bat](make.bat) script.
|
||||||
|
|
||||||
|
## Config files
|
||||||
|
