## # vcpkg_configure_make
##
## Configure configure for Debug and Release builds of a project.
##
## ## Usage
## ```cmake
## vcpkg_configure_make(
##     SOURCE_PATH <${SOURCE_PATH}>
##     [AUTOCONFIG]
##     [NO_DEBUG]
##     [SKIP_CONFIGURE]
##     [PROJECT_SUBPATH <${PROJ_SUBPATH}>]
##     [PRERUN_SHELL <${SHELL_PATH}>]
##     [OPTIONS <-DUSE_THIS_IN_ALL_BUILDS=1>...]
##     [OPTIONS_RELEASE <-DOPTIMIZE=1>...]
##     [OPTIONS_DEBUG <-DDEBUGGABLE=1>...]
## )
## ```
##
## ## Parameters
## ### SOURCE_PATH
## Specifies the directory containing the `configure`/`configure.ac`.
## By convention, this is usually set in the portfile as the variable `SOURCE_PATH`.
##
## ### PROJECT_SUBPATH
## Specifies the directory containing the ``configure`/`configure.ac`.
## By convention, this is usually set in the portfile as the variable `SOURCE_PATH`.
##
## ### SKIP_CONFIGURE
## Skip configure process
##
## ### AUTOCONFIG
## Need to use autoconfig to generate configure file.
##
## ### PRERUN_SHELL
## Script that needs to be called before configuration (do not use for batch files which simply call autoconf or configure)
##
## ### OPTIONS
## Additional options passed to configure during the configuration.
##
## ### OPTIONS_RELEASE
## Additional options passed to configure during the Release configuration. These are in addition to `OPTIONS`.
##
## ### OPTIONS_DEBUG
## Additional options passed to configure during the Debug configuration. These are in addition to `OPTIONS`.
##
## ## Notes
## This command supplies many common arguments to configure. To see the full list, examine the source.
