# vcpkg_cmake_config_fixup
|
|
|
|
Merge release and debug CMake targets and configs to support multiconfig generators.
|
|
|
|
Additionally corrects common issues with targets, such as absolute paths and incorrectly placed binaries.
|
|
|
|
```cmake
|
|
vcpkg_cmake_config_fixup(
|
|
[PACKAGE_NAME <name>]
|
|
[CONFIG_PATH <config-directory>]
|
|
[DO_NOT_DELETE_CONFIG_PATH_PARENT]
|
|
[NO_PREFIX_CORRECTION]
|
|
)
|
|
```
|
|
|
|
For many ports, `vcpkg_cmake_config_fixup()` on its own should work,
|
|
as `PACKAGE_NAME` defaults to `${PORT}` and `CONFIG_PATH` defaults to `share/${PACKAGE_NAME}`.
|
|
For ports where the package name passed to `find_package` is distinct from the port name,
|
|
`PACKAGE_NAME` should be changed to be that name instead.
|
|
For ports where the directory of the `*config.cmake` files cannot be set,
|
|
use the `CONFIG_PATH` to change the directory where the files come from.
|
|
|
|
By default the parent directory of CONFIG_PATH is removed if it is named "cmake".
|
|
Passing the `DO_NOT_DELETE_PARENT_CONFIG_PATH` option disable such behavior,
|
|
as it is convenient for ports that install
|
|
more than one CMake package configuration file.
|
|
|
|
The `NO_PREFIX_CORRECTION` option disables the correction of `_IMPORT_PREFIX`
|
|
done by vcpkg due to moving the config files.
|
|
Currently the correction does not take into account how the files are moved,
|
|
and applies a rather simply correction which in some cases will yield the wrong results.
|
|
|
|
## How it Works
|
|
|
|
1. Moves `/debug/<CONFIG_PATH>/*targets-debug.cmake` to `/share/${PACKAGE_NAME}`.
|
|
2. Removes `/debug/<CONFIG_PATH>/*config.cmake`.
|
|
3. Transform all references matching `/bin/*.exe` to `/tools/<port>/*.exe` on Windows.
|
|
4. Transform all references matching `/bin/*` to `/tools/<port>/*` on other platforms.
|
|
5. Fixes `${_IMPORT_PREFIX}` in auto generated targets.
|
|
6. Replace `${CURRENT_INSTALLED_DIR}` with `${_IMPORT_PREFIX}` in configs and targets.
|
|
|
|
## Examples
|
|
|
|
* [concurrentqueue](https://github.com/Microsoft/vcpkg/blob/master/ports/concurrentqueue/portfile.cmake)
|
|
* [curl](https://github.com/Microsoft/vcpkg/blob/master/ports/curl/portfile.cmake)
|
|
* [nlohmann-json](https://github.com/Microsoft/vcpkg/blob/master/ports/nlohmann-json/portfile.cmake)
