35 # This package tries to find an external muparser library, version
38 # MUPARSER_FOUND - muparser was found
39 # MUPARSER_INCLUDE_DIR - muparser include directory
40 # MUPARSER_LIBRARY - muparser library
41 # MUPARSER_LINKS_OK - muparser libraries link correctly
42 # MUPARSER_VERSION - muparser version string as "major.minor"
44 # CMake will search the CMAKE_PREFIX_PATH in the usual way, but if you
45 # need more control then setting MUPARSER_INCLUDE_DIR and MUPARSER_LIBRARY
46 # on the cmake command line to suitable values will work.
