Usage: $0 [OPTION]... [VAR=VALUE]...
Build Options:
--builddir=DIR place build files in directory [build]
--build-type=TYPE set CMake build type [RelWithDebInfo]:
- Debug: optimizations off, debug symbols + flags
- MinSizeRel: size optimizations, debugging off
- Release: optimizations on, debugging off
- RelWithDebInfo: optimizations on,
debug symbols on, debug flags off
--generator=GENERATOR CMake generator to use (see cmake --help)
Installation Directories:
--prefix=PREFIX installation directory [/usr/local/zeek]
Optional Features:
--enable-debug compile in debugging mode (like --build-type=Debug)
Required Packages in Non-Standard Locations:
--with-flex=PATH path to flex executable
--with-bison=PATH path to bison executable
Influential Environment Variables (only on first invocation
per build directory):
CC C compiler command
CFLAGS C compiler flags
CXX C++ compiler command
CXXFLAGS C++ compiler flags
