FindParasolid.cmake

# - try to find PARASOLID library
# Important note: If you are also using JtTk, do your
#  find_package(JtTk)
# first, to avoid runtime PK_* errors!
#
#  PARASOLID_LIBRARY_DIR, library search path
#  PARASOLID_INCLUDE_DIR, include search path
#  PARASOLID_{component}_LIBRARY, the library to link against
#  PARASOLID_FOUND, If false, do not try to use this library.
#
# Plural versions refer to this library and its dependencies, and
# are recommended to be used instead, unless you have a good reason.
#
# Requires these CMake modules:
#  CheckVersion
#  ListCombinations
#  ProgramFilesGlob
#  FindPackageHandleStandardArgs (known included with CMake >=2.6.2)
