# FindSTB - attempts to locate the stb single-file public domain
|
|
# libraries for C/C++
|
|
#
|
|
# This module defines the following variables (on success):
|
|
# STB_INCLUDE_DIRS - where to find stb_image.h
|
|
# STB_FOUND - if the library was successfully located
|
|
#
|
|
# It is trying a few standard installation locations, but can be customized
|
|
# with the following variables:
|
|
# STB_ROOT_DIR - root directory of a stb installation
|
|
# Headers are expected to be found in either:
|
|
# <STB_ROOT_DIR>/stb_image.h OR
|
|
# <STB_ROOT_DIR>/include/stb_image.h
|
|
# This variable can either be a cmake or environment
|
|
# variable. Note however that changing the value
|
|
# of the environment varible will NOT result in
|
|
# re-running the header search and therefore NOT
|
|
# adjust the variables set by this module.
