# vcpkg_buildpath_length_warning

Warns the user if their vcpkg installation path might be too long for the package they're installing.

```cmake
vcpkg_buildpath_length_warning(<N>)
```

`vcpkg_buildpath_length_warning` warns the user if the number of bytes in the
path to `buildtrees` is bigger than `N`. Note that this is simply a warning,
and isn't relied on for correctness.

[Qt] Update to 5.12.4 (#7667) * update to 5.12.4 * removed port qt5-modularscripts and split it functionality into more functions into qt5-base * added qt_port_hashes.cmake for simpler upgrade. * added optional VCPKG_QT_HOST_MKSPEC and VCPKG_QT_TARGET_MKSPEC to select QTs build mkspecs from a triplet * qt_<config>.conf are now copied from the build dir instead from the port dir * fixed freetype dependencies. * cleanup of vcpkg_qmake scripts. No strange/unclear replacements anymore. * introduced vcpkg_buildpath_length_warning * changed directory layout of the qt5 installation executables and mkspecs a bit. 2019-09-13 01:07:22 +08:00			`message(WARNING "${PORT}'s buildsystem uses very long paths and may fail on your system.\n"`
