#
# ---- Find Squish
# This module can be used to find Squish. Currently Squish version 3 is supported.
#
# ---- Variables and Macros
#  SQUISH_FOUND                    If false, don't try to use Squish
#  SQUISH_VERSION                  The full version of Squish found
#  SQUISH_VERSION_MAJOR            The major version of Squish found
#  SQUISH_VERSION_MINOR            The minor version of Squish found
#  SQUISH_VERSION_PATCH            The patch version of Squish found
#
#  SQUISH_INSTALL_DIR              The Squish installation directory (containing bin, lib, etc)
#  SQUISH_SERVER_EXECUTABLE        The squishserver executable
#  SQUISH_CLIENT_EXECUTABLE        The squishrunner executable
#
#  SQUISH_INSTALL_DIR_FOUND        Was the install directory found?
#  SQUISH_SERVER_EXECUTABLE_FOUND  Was the server executable found?
#  SQUISH_CLIENT_EXECUTABLE_FOUND  Was the client executable found?
#
# macro SQUISH_V3_ADD_TEST(testName applicationUnderTest testCase envVars testWrapper)
#   Use this macro to add a test using Squish 3.x.
#
# ---- Typical Use
#  enable_testing()
#  find_package(Squish)
#  if (SQUISH_FOUND)
#    SQUISH_ADD_TEST(myTestName myApplication testCase envVars testWrapper)
#  endif ()
#
# macro SQUISH_ADD_TEST(testName applicationUnderTest testCase envVars testWrapper)
#   This is deprecated. Use SQUISH_V3_ADD_TEST() if you are using Squish 3.x instead.
