1203\`configure' configures RcppArmadillo 0.10.7.5.0 to adapt to many kinds of systems.
1204
1205Usage: $0 [OPTION]... [VAR=VALUE]...
1206
1207To assign environment variables (e.g., CC, CFLAGS...), specify them as
1208VAR=VALUE.  See below for descriptions of some of the useful variables.
1209
1210Defaults for the options are specified in brackets.
1211
1212Configuration:
1213  -h, --help              display this help and exit
1214      --help=short        display options specific to this package
1215      --help=recursive    display the short help of all the included packages
1216  -V, --version           display version information and exit
1217  -q, --quiet, --silent   do not print \`checking ...' messages
1218      --cache-file=FILE   cache test results in FILE [disabled]
1219  -C, --config-cache      alias for \`--cache-file=config.cache'
1220  -n, --no-create         do not create output files
1221      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1222
1223Installation directories:
1224  --prefix=PREFIX         install architecture-independent files in PREFIX
1225                          [$ac_default_prefix]
1226  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1227                          [PREFIX]
1228
1229By default, \`make install' will install all the files in
1230\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1231an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1232for instance \`--prefix=\$HOME'.
1233
1234For better control, use the options below.
1235
1236Fine tuning of the installation directories:
1237  --bindir=DIR            user executables [EPREFIX/bin]
1238  --sbindir=DIR           system admin executables [EPREFIX/sbin]

1269Some influential environment variables:
1270  CXX         C++ compiler command
1271  CXXFLAGS    C++ compiler flags
1272  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1273              nonstandard directory <lib dir>
1274  LIBS        libraries to pass to the linker, e.g. -l<library>
1275  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1276              you have headers in a nonstandard directory <include dir>
1277  CXXCPP      C++ preprocessor
1278
1279Use these variables to override the choices made by `configure' or to help
1280it to find libraries and programs with nonstandard names/locations.
