# Most of the code from this point onwards is related to populating the
# following variables:
#   PA_PUBLIC_INCLUDES - This contains the list of public PortAudio header
#       files. These files will be copied into /include paths on Unix'y
#       systems when "make install" is invoked.
#   PA_PRIVATE_INCLUDES - This contains the list of header files which
#       are not part of PortAudio, but are required by the various hostapis.
#       It is only used by CMake IDE generators (like Visual Studio) to
#       provide quick-links to useful headers. It has no impact on build
#       output.
#   PA_PRIVATE_INCLUDE_PATHS - This contains the list of include paths which
#       will be passed to the compiler while PortAudio is being built which
#       are not required by applications using the PortAudio API.
#   PA_PRIVATE_COMPILE_DEFINITIONS - This contains a list of preprocessor
#       macro definitions which will be set when compiling PortAudio source
#       files.
#   PA_SOURCES - This contains the list of source files which will be built
#       into the static and shared PortAudio libraries.
#   PA_NON_UNICODE_SOURCES - This also contains a list of source files which
#       will be build into the static and shared PortAudio libraries. However,
#       these sources will not have any unicode compiler definitions added
#       to them. This list should only contain external source dependencies.
#   PA_EXTRA_SHARED_SOURCES - Contains a list of extra files which will be
#       associated only with the shared PortAudio library. This only seems
#       relevant for Windows shared libraries which require a list of export
#       symbols.
# Where other PA_* variables are set, these are almost always only used to
# preserve the historic SOURCE_GROUP behavior (which again only has an impact
# on IDE-style generators for visual appearance) or store the output of
# find_library() calls.
