Build a cmake project.
|
||
|
|
|
||
|
|
```cmake
|
||
|
|
vcpkg_cmake_build(
|
||
|
|
[TARGET <target>]
|
||
|
|
[LOGFILE_BASE <base>]
|
||
|
|
[DISABLE_PARALLEL]
|
||
|
|
[ADD_BIN_TO_PATH]
|
||
|
|
)
|
||
|
|
```
|
||
|
|
|
||
|
|
`vcpkg_cmake_build` builds an already-configured cmake project.
|
||
|
|
You can use the alias [`vcpkg_cmake_install()`] function
|
||
|
|
if your CMake build system supports the `install` TARGET,
|
||
|
|
and this is something we recommend doing whenever possible.
|
||
|
|
Otherwise, you can use `TARGET` to set the target to build.
|
||
|
|
This function defaults to not passing a target to cmake.
|
||
|
|
|
||
|
|
`LOGFILE_BASE` is used to set the base of the logfile names;
|
||
|
|
by default, this is `build`, and thus the logfiles end up being something like
|
||
|
|
`build-x86-windows-dbg.log`; if you use `vcpkg_cmake_install`,
|
||
|
|
this is set to `install`, so you'll get log names like `install-x86-windows-dbg.log`.
|
||
|
|
|
||
|
|
For build systems that are buggy when run in parallel,
|
||
|
|
using `DISABLE_PARALLEL` will run the build with only one job.
|
||
|
|
|
||
|
|
Finally, `ADD_BIN_TO_PATH` adds the appropriate (either release or debug)
|
||
|
|
`bin/` directories to the path during the build,
|
||
|
|
such that executables run during the build will be able to access those DLLs.
