vcpkg_cmake_get_vars
The latest version of this document lives in the vcpkg repo.
Runs a cmake configure with a dummy project to extract certain cmake variables
Usage
vcpkg_cmake_get_vars(<out-var>)
vcpkg_cmake_get_vars(<out-var>) sets <out-var> to
a path to a generated CMake file, with the detected CMAKE_* variables
re-exported as VCPKG_DETECTED_CMAKE_*.
Additionally sets, for RELEASE and DEBUG:
- VCPKG_COMBINED_CXX_FLAGS_
- VCPKG_COMBINED_C_FLAGS_
- VCPKG_COMBINED_SHARED_LINKER_FLAGS_
- VCPKG_COMBINED_STATIC_LINKER_FLAGS_
- VCPKG_COMBINED_EXE_LINKER_FLAGS_
Most users should use these pre-combined flags instead of attempting
to read the VCPKG_DETECTED_* flags directly.
Notes
Avoid usage in portfiles.
All calls to vcpkg_cmake_get_vars will result in the same output file;
the output file is not generated multiple times.
Basic Usage
vcpkg_cmake_get_vars(cmake_vars_file)
include("${cmake_vars_file}")
message(STATUS "detected CXX flags: ${VCPKG_DETECTED_CMAKE_CXX_FLAGS}")
