'configure' configures NCPA Propagation Modeling Suite 2.2.0 to adapt to many kinds of systems.

Usage: $0 [OPTION]... [VAR=VALUE]...

To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE.  See below for descriptions of some of the useful variables.

Defaults for the options are specified in brackets.

Configuration:
  -h, --help              display this help and exit
      --help=short        display options specific to this package
      --help=recursive    display the short help of all the included packages
  -V, --version           display version information and exit
  -q, --quiet, --silent   do not print 'checking ...' messages
      --cache-file=FILE   cache test results in FILE [disabled]
  -C, --config-cache      alias for '--cache-file=config.cache'
  -n, --no-create         do not create output files
      --srcdir=DIR        find the sources in DIR [configure dir or '..']

Installation directories:
  --prefix=PREFIX         install architecture-independent files in PREFIX
                          [$ac_default_prefix]
  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
                          [PREFIX]

By default, 'make install' will install all the files in
'$ac_default_prefix/bin', '$ac_default_prefix/lib' etc.  You can specify
an installation prefix other than '$ac_default_prefix' using '--prefix',
for instance '--prefix=\$HOME'.

For better control, use the options below.

Fine tuning of the installation directories:
  --bindir=DIR            user executables [EPREFIX/bin]
  --sbindir=DIR           system admin executables [EPREFIX/sbin]
  --libexecdir=DIR        program executables [EPREFIX/libexec]
  --sysconfdir=DIR        read-only single-machine data [PREFIX/etc]
  --sharedstatedir=DIR    modifiable architecture-independent data [PREFIX/com]
  --localstatedir=DIR     modifiable single-machine data [PREFIX/var]
  --runstatedir=DIR       modifiable per-process data [LOCALSTATEDIR/run]
  --libdir=DIR            object code libraries [EPREFIX/lib]
  --includedir=DIR        C header files [PREFIX/include]
  --oldincludedir=DIR     C header files for non-gcc [/usr/include]
  --datarootdir=DIR       read-only arch.-independent data root [PREFIX/share]
  --datadir=DIR           read-only architecture-independent data [DATAROOTDIR]

Optional Features:
  --disable-option-checking  ignore unrecognized --enable/--with options
  --disable-FEATURE       do not include FEATURE (same as --enable-FEATURE=no)
  --enable-FEATURE[=ARG]  include FEATURE [ARG=yes]
  --enable-localpetscmpi  Build PETSc/SLEPc without MPI support
  --enable-autodependencies
                          Attempt to install dependencies using the default
                          package manager (Linux only). Currently supported
                          package managers: apt, yum

  --enable-compilerwarnings
                          Don't suppress additional compiler warnings
                          (development only)


Optional Packages:
  --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
  --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
  --with-localpetsc       Attempt to build a PETSc instance local to the
                          $PACKAGE_NAME installation

  --with-localslepc       Attempt to build a SLEPc instance local to the
                          $PACKAGE_NAME installation. Automatically set to
                          'yes' if --with-localpetsc is specified

  --with-localpetscdebug  Build the debug version of PETSc/SLEPc instead of
                          the default optimized version
  --with-blas=<lib>       use BLAS library <lib>

Some influential environment variables:
  local_petsc_dir
              Override default local PETSc installation directory
  local_slepc_dir
              Override default local SLEPc installation directory
  local_petsc_arch_real
              Override automatic PETSc real architecture name
  local_petsc_arch_complex
              Override automatic PETSc complex architecture name
  local_petsc_branch
              Override automatic PETSc branch
  local_slepc_branch
              Override automatic (or outdated) SLEPc version number
  CXX         C++ compiler command
  CXXFLAGS    C++ compiler flags
  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
              nonstandard directory <lib dir>
  LIBS        libraries to pass to the linker, e.g. -l<library>
  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
              you have headers in a nonstandard directory <include dir>
  CC          C compiler command
  CFLAGS      C compiler flags
  CPP         C preprocessor
  F77         Fortran 77 compiler command
  FFLAGS      Fortran 77 compiler flags

Use these variables to override the choices made by 'configure' or to help
it to find libraries and programs with nonstandard names/locations.

                type name.

                Although C99 requires bool, true, and false to be macros,
                C23 and C++11 overrule that, so do not test for that.
                Although C99 requires __bool_true_false_are_defined and
                _Bool, C23 says they are obsolescent, so do not require
