z_vcpkg_get_cmake_vars

The latest version of this document lives in the vcpkg repo.

Only for internal use in vcpkg helpers. Behavior and arguments will change without notice. Runs a cmake configure with a dummy project to extract certain cmake variables

Usage

z_vcpkg_get_cmake_vars(<out-var>)

z_vcpkg_get_cmake_vars(cmake_vars_file) sets <out-var> to a path to a generated CMake file, with the detected CMAKE_* variables re-exported as VCPKG_DETECTED_*.

Notes

Avoid usage in portfiles.

All calls to z_vcpkg_get_cmake_vars will result in the same output file; the output file is not generated multiple times.

Examples

• vcpkg_configure_make

Basic Usage

z_vcpkg_get_cmake_vars(cmake_vars_file)
include("${cmake_vars_file}")
message(STATUS "detected CXX flags: ${VCPKG_DETECTED_CXX_FLAGS}")
