# Initialize some variables set by options.

--disable-libtool-lock avoid locking (might break parallel builds)
--disable-largefile omit support for large files
- --enable-cet enable Intel CET in target libraries [default=no]
+ --enable-cet enable Intel CET in target libraries [default=auto]
--enable-host-shared build host code as shared libraries
+ --enable-cet enable Intel CET in host libraries [default=auto]
Optional Packages:
--with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
you have headers in a nonstandard directory <include dir>
CPP C preprocessor
OBJCOPY location of objcopy
+ DSYMUTIL location of dsymutil
+ NM location of nm
Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.
