# Module to find IlmBase
|
||
|
#
|
||
|
# This module will first look into the directories defined by the variables:
|
||
|
# - ILMBASE_HOME, ILMBASE_VERSION, ILMBASE_LIB_AREA
|
||
|
#
|
||
|
# It also supports non-standard names for the library components.
|
||
|
#
|
||
|
# To use a custom IlmBase:
|
||
|
# - Set the variable ILMBASE_CUSTOM to True
|
||
|
# - Set the variable ILMBASE_CUSTOM_LIBRARIES to a list of the libraries to
|
||
|
# use, e.g. "SpiImath SpiHalf SpiIlmThread SpiIex"
|
||
|
# - Optionally set the variable ILMBASE_CUSTOM_INCLUDE_DIR to any
|
||
|
# particularly weird place that the OpenEXR/*.h files may be found
|
||
|
# - Optionally set the variable ILMBASE_CUSTOM_LIB_DIR to any
|
||
|
# particularly weird place that the libraries files may be found
|
||
|
#
|
||
|
# This module defines the following variables:
|
||
|
#
|
||
|
# ILMBASE_INCLUDE_DIR - where to find half.h, IlmBaseConfig.h, etc.
|
||
|
# ILMBASE_LIBRARIES - list of libraries to link against when using IlmBase.
|
||
|
# ILMBASE_FOUND - True if IlmBase was found.
|
||
|
|
||
|
# Other standarnd issue macros
