Summary	0015856: CLEAN_NO_CUSTOM is not supported for the Ninja (and MSVC?) generators
Description	The directory property CLEAN_NO_CUSTOM does not work as advertised for the Ninja generator. The generated outputs are still removed. Apparently MSVC is also affected[1], but I have not confirmed this. https://cmake.org/pipermail/cmake/2011-May/044214.html [^]
Steps To Reproduce	# CMakeLists.txt cmake_minimum_required(VERSION 2.8.3) project(test LANGUAGES) set_directory_properties(PROPERTIES CLEAN_NO_CUSTOM 1) add_custom_command(OUTPUT test.txt COMMAND touch test.txt) add_custom_target(foo ALL DEPENDS test.txt) # make keeps "test.txt" (rm -rf m && mkdir $_ && cd $_ && cmake .. && make && make clean && ls) # ninja removes "test.txt" (rm -rf n && mkdir $_ && cd $_ && cmake -GNinja .. && ninja && ninja clean && ls)
Additional Information	Lacking a per-target option to prevent output removal (bug 0009505), I was trying to implement it as follows: - set CLEAN_NO_CUSTOM on the directory to prevent removal of a single source file (generated using the add_custom_commands() command) - put all other generated files in ADDITIONAL_MAKE_CLEAN_FILES except that it does not work due to this bug, the outputs are still removed.
