1 # CMake script for finding HOOMD and setting up all needed compile options to create and link a plugin library
3 # Variables taken as input to this module:
4 # HOOMD_ROOT : location to look for HOOMD, if it is not in the system path
6 # Variables defined by this module:
7 # FOUND_HOOMD : set to true if HOOMD is found
8 # HOOMD_LIBRARIES : a list of all libraries needed to link to to access hoomd (uncached)
9 # HOOMD_INCLUDE_DIR : a list of all include directories that need to be set to include HOOMD
10 # HOOMD_BIN_DIR : the directory containing the hoomd runner executable
11 # HOOMD_LIB : a cached var locating the hoomd library to link to
13 # various ENABLE_ flags translated from hoomd_config.h so this plugin build can match the ABI of the installed hoomd
15 # as a convenience (for the intended purpose of this find script), all include directories and definitions needed
16 # to compile with all the various libs (boost, python, winsoc, etc...) are set within this script
