## # vcpkg_check_features
|
|
## Check if one or more features are a part of a package installation.
|
|
##
|
|
## ## Usage
|
|
## ```cmake
|
|
## vcpkg_check_features(
|
|
## OUT_FEATURE_OPTIONS <FEATURE_OPTIONS>
|
|
## [FEATURES
|
|
## <cuda> <WITH_CUDA>
|
|
## [<opencv> <WITH_OPENCV>]
|
|
## ...]
|
|
## [INVERTED_FEATURES
|
|
## <cuda> <IGNORE_PACKAGE_CUDA>
|
|
## [<opencv> <IGNORE_PACKAGE_OPENCV>]
|
|
## ...]
|
|
## )
|
|
## ```
|
|
## `vcpkg_check_features()` accepts these parameters:
|
|
##
|
|
## * `OUT_FEATURE_OPTIONS`:
|
|
## An output variable, the function will clear the variable passed to `OUT_FEATURE_OPTIONS`
|
|
## and then set it to contain a list of option definitions (`-D<OPTION_NAME>=ON|OFF`).
|
|
##
|
|
## This should be set to `FEATURE_OPTIONS` by convention.
|
|
##
|
|
## * `FEATURES`:
|
|
## A list of (`FEATURE_NAME`, `OPTION_NAME`) pairs.
|
|
## For each `FEATURE_NAME` a definition is added to `OUT_FEATURE_OPTIONS` in the form of:
|
|
##
|
|
## * `-D<OPTION_NAME>=ON`, if a feature is specified for installation,
|
|
## * `-D<OPTION_NAME>=OFF`, otherwise.
|
|
##
|
|
## * `INVERTED_FEATURES`:
|
|
## A list of (`FEATURE_NAME`, `OPTION_NAME`) pairs, uses reversed logic from `FEATURES`.
|
|
## For each `FEATURE_NAME` a definition is added to `OUT_FEATURE_OPTIONS` in the form of:
|
|
##
|
|
## * `-D<OPTION_NAME>=OFF`, if a feature is specified for installation,
|
|
## * `-D<OPTION_NAME>=ON`, otherwise.
|
|
##
|
|
##
|
|
## ## Notes
|
|
##
|
|
## The `FEATURES` name parameter can be omitted if no `INVERTED_FEATURES` are used.
|
|
##
|
|
## At least one (`FEATURE_NAME`, `OPTION_NAME`) pair must be passed to the function call.
|
|
##
|
|
## Arguments passed to `FEATURES` and `INVERTED_FEATURES` are not validated to prevent duplication.
|
|
## If the same (`FEATURE_NAME`, `OPTION_NAME`) pair is passed to both lists,
|
|
## two conflicting definitions are added to `OUT_FEATURE_OPTIONS`.
|
|
##
|
|
##
|
|
## ## Examples
|
|
##
|
|
## ### Example 1: Regular features
|
|
##
|
|
## ```cmake
|
|
## $ ./vcpkg install mimalloc[asm,secure]
|
|
##
|
|
## # ports/mimalloc/portfile.cmake
|
|
## vcpkg_check_features(OUT_FEATURE_OPTIONS FEATURE_OPTIONS
|
|
## # Keyword FEATURES is optional if INVERTED_FEATURES are not used
|
|
## asm MI_SEE_ASM
|
|
## override MI_OVERRIDE
|
|
## secure MI_SECURE
|
|
## )
|
|
##
|
|
## vcpkg_configure_cmake(
|
|
## SOURCE_PATH ${SOURCE_PATH}
|
|
## PREFER_NINJA
|
|
## OPTIONS
|
|
## # Expands to "-DMI_SEE_ASM=ON; -DMI_OVERRIDE=OFF; -DMI_SECURE=ON"
|
|
## ${FEATURE_OPTIONS}
|
|
## )
|
|
## ```
|
|
##
|
|
## ### Example 2: Inverted features
|
|
##
|
|
## ```cmake
|
|
## $ ./vcpkg install cpprestsdk[websockets]
|
|
##
|
|
## # ports/cpprestsdk/portfile.cmake
|
|
## vcpkg_check_features(OUT_FEATURE_OPTIONS FEATURE_OPTIONS
|
|
## INVERTED_FEATURES # <- Keyword INVERTED_FEATURES required
|
|
## brotli CPPREST_EXCLUDE_BROTLI
|
|
## websockets CPPREST_EXCLUDE_WEBSOCKETS
|
|
## )
|
|
##
|
|
## vcpkg_configure_cmake(
|
|
## SOURCE_PATH ${SOURCE_PATH}
|
|
## PREFER_NINJA
|
|
## OPTIONS
|
|
## # Expands to "-DCPPREST_EXCLUDE_BROTLI=ON; -DCPPREST_EXCLUDE_WEBSOCKETS=OFF"
|
|
## ${FEATURE_OPTIONS}
|
|
## )
|
|
## ```
|
|
##
|
|
## ### Example 3: Set multiple options for same feature
|
|
##
|
|
## ```cmake
|
|
## $ ./vcpkg install pcl[cuda]
|
|
##
|
|
## # ports/pcl/portfile.cmake
|
|
## vcpkg_check_features(OUT_FEATURE_OPTIONS FEATURE_OPTIONS
|
|
## cuda WITH_CUDA
|
|
## cuda BUILD_CUDA
|
|
## cuda BUILD_GPU
|
|
## )
|
|
##
|
|
## vcpkg_configure_cmake(
|
|
## SOURCE_PATH ${SOURCE_PATH}
|
|
## PREFER_NINJA
|
|
## OPTIONS
|
|
## # Expands to "-DWITH_CUDA=ON; -DBUILD_CUDA=ON; -DBUILD_GPU=ON"
|
|
## ${FEATURE_OPTIONS}
|
|
## )
|
|
## ```
|
|
##
|
|
## ### Example 4: Use regular and inverted features
|
|
##
|
|
## ```cmake
|
|
## $ ./vcpkg install rocksdb[tbb]
|
|
##
|
|
## # ports/rocksdb/portfile.cmake
|
|
## vcpkg_check_features(OUT_FEATURE_OPTIONS FEATURE_OPTIONS
|
|
## FEATURES # <- Keyword FEATURES is required because INVERTED_FEATURES are being used
|
|
## tbb WITH_TBB
|
|
## INVERTED_FEATURES
|
|
## tbb ROCKSDB_IGNORE_PACKAGE_TBB
|
|
## )
|
|
##
|
|
## vcpkg_configure_cmake(
|
|
## SOURCE_PATH ${SOURCE_PATH}
|
|
## PREFER_NINJA
|
|
## OPTIONS
|
|
## # Expands to "-DWITH_TBB=ON; -DROCKSDB_IGNORE_PACKAGE_TBB=OFF"
|
|
## ${FEATURE_OPTIONS}
|
|
## )
|
|
## ```
|
|
##
|
|
