# On Windows certain libraries have two sets of binaries: one for debug builds and one for
|
|
# release builds. The root of this requirement goes into ABI, I believe, but that's outside
|
|
# of a scope of this comment.
|
|
#
|
|
# CMake have a native way of dealing with this, which is specifying what build type the
|
|
# libraries are provided for:
|
|
#
|
|
# target_link_libraries(target optimized|debug|general <libraries>)
|
|
#
|
|
# The build type is to be provided as a separate argument to the function.
|
|
#
|
|
# CMake's variables for libraries will contain build type in such cases. For example:
|
|
#
|
|
# set(FOO_LIBRARIES optimized libfoo.lib debug libfoo_d.lib)
|
|
#
|
|
# Complications start with a single argument for library_deps: all the elements are being
|
|
# put to a list: "${FOO_LIBRARIES}" will become "optimized;libfoo.lib;debug;libfoo_d.lib".
|
|
# This makes it impossible to pass it as-is to target_link_libraries since it will treat
|
|
# this argument as a list of libraries to be linked against, causing missing libraries
|
|
# for optimized.lib.
|
|
#
|
|
# What this code does it traverses library_deps and extracts information about whether
|
|
# library is to provided as general, debug or optimized. This is a little state machine which
|
|
# keeps track of which build type library is to provided for:
|
|
#
|
|
# - If "debug" or "optimized" word is found, the next element in the list is expected to be
|
|
# a library which will be passed to target_link_libraries() under corresponding build type.
|
|
#
|
|
# - If there is no "debug" or "optimized" used library is specified for all build types.
|
|
#
|
|
# NOTE: If separated libraries for debug and release are needed every library is the list are
|
|
# to be prefixed explicitly.
|
|
#
|
|
# Use: "optimized libfoo optimized libbar debug libfoo_d debug libbar_d"
|
|
# NOT: "optimized libfoo libbar debug libfoo_d libbar_d"
|
|
#
|
|
# TODO(sergey): This is the same as Blender's side CMake. Find a way to avoid duplication
|
|
# somehow in a way which allows to have Cycles standalone.
