(Minor update) Moved some utilities to a separate file. 2009-04-10 05:16:28 +08:00			`# File containing various utilities`

CMake: Set at most one SSL library Ref: https://github.com/curl/curl/pull/1228 2017-02-21 08:33:53 +08:00			`# Returns a list of arguments that evaluate to true`
CMake: Remove unused 'output_var' from 'collect_true' Variable 'output_var' is not used and can be removed. Function 'collect_true' renamed to 'count_true'. 2018-07-05 18:21:57 +08:00			`function(count_true output_count_var)`
CMake: clean up and improve build procedures - remove check for unsupported old CMake versions - do not link to c-ares library twice - modernize custom Find modules - FindLibSSH2: - pass version to FPHSA to show it in the output - use LIBSSH2_VERSION define to extract the version number in one shot. This variable exists in the header for 10 years. - remove unneeded code - FindNGHTTP2.cmake: - drop needless FPHSA argument - mark found variables as advanced - FindNSS.cmake: - show version number - FindCARES.cmake: - drop default paths - use FPHSA instead of checking things by hand - remove needless explict variable dereference - simplify count_true() - allow all policies up to version 3.16 to be set to NEW - do not rerun check for -Wstrict-aliasing=3 every time In contrast to every other compiler flag this has a = in it, which CMake can't have in a variable name. - only read the interesting strings from curlver.h Reviewed-by: Peter Wu Closes https://github.com/curl/curl/pull/4975 2020-02-24 20:34:54 +08:00			`set(lst_len 0)`
