# pm_common/CMakeLists.txt -- how to build portmidi library
# creates the portmidi library
# exports PM_NEEDED_LIBS to parent. It seems that PM_NEEDED_LIBS for
# Linux should include Thread::Thread and ALSA::ALSA, but these
# are not visible in other CMake files, even though the portmidi
# target is. Therefore, Thread::Thread is replaced by
# CMAKE_THREAD_LIBS_INIT and ALSA::ALSA is replaced by ALSA_LIBRARIES.
# Is there a better way to do this? Maybe this whole file should be
# at the parent level.
# Support alternative name for static libraries to avoid confusion.
# (In particular, Xcode has automatically converted portmidi.a to
# portmidi.dylib without warning, so using portmidi-static.a eliminates
# this possibility, but default for all libs is "portmidi"):
