Subject: apps: use CMake check for getopt.h
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=a7b34a299b5e8fe6e0e4047a14da36085966112e;p=thirdparty%2Fjson-c.git

apps: use CMake check for getopt.h
Add CMake detection for getopt.h and update json_parse.c to include it
only when HAVE_GETOPT_H is defined. Fixes AIX build failure.
