# vcpkg_configure_cmake
Configure CMake for Debug and Release builds of a project.
## Usage
```cmake
vcpkg_configure_cmake(
SOURCE_PATH <${SOURCE_PATH}>
[PREFER_NINJA]
[DISABLE_PARALLEL_CONFIGURE]
[NO_CHARSET_FLAG]
[GENERATOR <"NMake Makefiles">]
[OPTIONS <-DUSE_THIS_IN_ALL_BUILDS=1>...]
[OPTIONS_RELEASE <-DOPTIMIZE=1>...]
[OPTIONS_DEBUG <-DDEBUGGABLE=1>...]
)
```
## Parameters
### SOURCE_PATH
Specifies the directory containing the `CMakeLists.txt`.
By convention, this is usually set in the portfile as the variable `SOURCE_PATH`.
### PREFER_NINJA
Indicates that, when available, Vcpkg should use Ninja to perform the build.
This should be specified unless the port is known to not work under Ninja.
### DISABLE_PARALLEL_CONFIGURE
Disables running the CMake configure step in parallel.
This is needed for libraries which write back into their source directory during configure.
This also disables CMAKE_DISABLE_SOURCE_CHANGES.
### NO_CHARSET_FLAG
Disables passing `utf-8` as the default character set to `CMAKE_C_FLAGS` and `CMAKE_CXX_FLAGS`.
This is needed for libraries that set their own source code's character set.
### GENERATOR
Specifies the precise generator to use.
This is useful if some project-specific buildsystem has been wrapped in a cmake script that won't perform an actual build.
If used for this purpose, it should be set to `"NMake Makefiles"`.
### OPTIONS
Additional options passed to CMake during the configuration.
### OPTIONS_RELEASE
Additional options passed to CMake during the Release configuration. These are in addition to `OPTIONS`.
### OPTIONS_DEBUG
Additional options passed to CMake during the Debug configuration. These are in addition to `OPTIONS`.
