# Modified from FindReadline.cmake (PH Feb 2012)
pcre2test: allow using readline headers for libedit (#99) At least in OpenBSD, there is a libedit library in base, but without public headers. Public headers for readline are available but since 15db5d36 (pcre2test: avoid using readline headers with libedit, 2022-04-07) won't be picked up automatically. Allow pointing cmake to those headers by doing (for example): $ cmake -DEDITLINE_INCLUDE_DIR=/usr/include/readline Or using custom CPPFLAGS with configure (for example): $ CPPFLAGS=-I/usr/include/readline ./configure --enable-pcre2test-libedit Since the headers from readline.h would be otherwise incomplete, detect that case and pull the extra headers that are required automagically and while at it, cleanup the NCURSES dependency that was unnecessarily copied from readline.

pcre2test: really allow using libedit when enabled (#96) * pcre2test: use the right header for libedit in FreeBSD with autoconf When `./configure --enable-pcre2test-libedit` is used in FreeBSD, the resulting test will succeed but won't set the necessary flag to distinguish between libedit and readline header files, therefore using readline's at built time (if installed) Consolidate all header tests into one and use instead the corresponding autogenerated defines to check for each possibility. * pcre2test: really allow libedit with cmake Using cmake to configure and enable linking pcre2test with libedit, could result in a broken build, because the header used was instead pointing to readline. In cases were the build will succeed (because both libraries were available), it would likely show warnings, because several history functions were being used without declarations, since readline requires including "history.h" for those. Additionally, since PCRE2_SUPPORT_READLINE is ON by default (unlike configure), turning PCRE2_SUPPORT_LIBEDIT=ON, would require setting that other option to OFF explicitly (even if readline wasn't available) or the setup would abort. Lastly, in systems with no default sysroot (ex: macOS), the use of absolute paths for searching for libedit's readline.h could fail so use instead relative PATH_SUFFIXES. * pcre2test: avoid using readline headers with libedit When asked to enable libedit in a system that ALSO has readline, the headers of the former would be found and used by the earlier. While that would mostly work, some functions will be missing definitions (which is forbidden in C99), so instead abort the configuration and let the user provide for them.
