# Find stb
|
|
# ==============================================================================
|
|
# This module fetches the stb single-file public domain libraries.
|
|
#
|
|
# Targets provided:
|
|
# stb::stb - The stb library target
|
|
#
|
|
# Variables set:
|
|
# stb_FOUND - TRUE if stb is available
|
|
# stb_LIBRARIES - The stb library target (stb::stb)
|
|
# stb_INCLUDE_DIR - Include directories for stb
|
|
# stb_VERSION - Version of stb (commit-based)
|
|
#
|
|
# Usage notes:
|
|
# stb headers are header-only but require an implementation macro to be
|
|
# defined in exactly ONE translation unit (.cpp file) before including the
|
|
# header, e.g.:
|
|
#
|
|
# #define STB_IMAGE_IMPLEMENTATION
|
|
# #include <stb_image.h>
|
|
#
|
|
# Each stb header has its own implementation macro. Do NOT define the macro
|
|
# in header files or in more than one translation unit or you will get
|
|
# duplicate symbol linker errors.
