InstallRules: added new variable to disable generation of install rules

The boolean variable CMAKE_SKIP_INSTALL_RULES
allows disabling generation of install rules for projects which don't
want them.

+# This directory contains tests that run CMake to configure a project
+# but do not actually build anything.  To add a test:
+#
+# 1.) Add a subdirectory named for the test.
+#
+# 2.) Call add_RunCMake_test and pass the test directory name.
+#
+# 3.) Create a RunCMakeTest.cmake script in the directory containing
+#   include(RunCMake)
+#   run_cmake(SubTest1)
+#   ...
+#   run_cmake(SubTestN)
+# where SubTest1..SubTestN are sub-test names each corresponding to
+# an independent CMake run and project configuration.
+#
+# 3.) Create a CMakeLists.txt file in the directory containing
+#   cmake_minimum_required(...)
+#   project(${RunCMake_TEST} NONE) # or languages needed
+#   include(${RunCMake_TEST}.cmake)
+# where "${RunCMake_TEST}" is literal.  A value for RunCMake_TEST
+# will be passed to CMake by the run_cmake macro when running each
+# sub-test.
+#
+# 4.) Create a <SubTest>.cmake file for each sub-test named above
+# containing the actual test code.  Optionally create files
+# containing expected test results:
+#   <SubTest>-result.txt  = Process result expected if not "0"
+#   <SubTest>-stdout.txt  = Regex matching expected stdout content
+#   <SubTest>-stderr.txt  = Regex matching expected stderr content
+#   <SubTest>-check.cmake = Custom result check
+# Note that trailing newlines will be stripped from actual and expected test
+# output before matching against the stdout and stderr expressions.
+# The code in <SubTest>-check.cmake may use variables
+#   RunCMake_TEST_SOURCE_DIR = Top of test source tree
+#   RunCMake_TEST_BINARY_DIR = Top of test binary tree
+# and an failure must store a message in RunCMake_TEST_FAILED.
