The latest version of this document lives in the vcpkg repo.
Configure a CMake buildsystem.
vcpkg_cmake_configure(
SOURCE_PATH <source-path>
[LOGFILE_BASE <logname-base>]
[DISABLE_PARALLEL_CONFIGURE]
[NO_CHARSET_FLAG]
[WINDOWS_USE_MSBUILD]
[GENERATOR <generator>]
[OPTIONS
<configure-setting>...]
[OPTIONS_RELEASE
<configure-setting>...]
[OPTIONS_DEBUG
<configure-setting>...]
)
vcpkg_cmake_configure configures a CMake build system for use with
vcpkg_cmake_buildsystem_build and vcpkg_cmake_buildsystem_install.
source-path is where the source is located; by convention,
this is usually ${SOURCE_PATH}, which is set by one of the vcpkg_from_* functions.
This function configures the build system for both Debug and Release builds by default,
assuming that VCPKG_BUILD_TYPE is not set; if it is, then it will only configure for
that build type.
Use the OPTIONS argument to set the configure settings for both release and debug,
and use OPTIONS_RELEASE and OPTIONS_DEBUG to set the configure settings for
release only and debug only respectively.
By default, when possible, vcpkg_cmake_configure uses ninja-build
as its build system. If the WINDOWS_USE_MSBUILD argument is passed, then
vcpkg_cmake_configure will use a Visual Studio generator on Windows;
on every other platform, vcpkg_cmake_configure just uses Ninja.
Additionally, one may pass the specific generator a port should use with GENERATOR.
This is useful if some project-specific buildsystem
has been wrapped in a CMake build system that doesn't perform an actual build.
If used for this purpose, it should be set to "NMake Makefiles".
vcpkg_cmake_buildsystem_build and install do not support this being set to anything
except for NMake.
For libraries which cannot be configured in parallel,
pass the DISABLE_PARALLEL_CONFIGURE flag. This is needed, for example,
if the library's build system writes back into the source directory during configure.
This also disables the CMAKE_DISABLE_SOURCE_CHANGES option.
By default, this function adds flags to CMAKE_C_FLAGS and CMAKE_CXX_FLAGS
which set the default character set to utf-8 for MSVC.
If the library sets its own code page, pass the NO_CHARSET_FLAG option.
LOGFILE_BASE is used to set the base of the logfile names;
by default, this is config, and thus the logfiles end up being something like
config-x86-windows-dbg.log. You can set it to anything you like;
if you set it to config-the-first,
you'll get something like config-the-first-x86-windows.dbg.log.
