# vcpkg_check_linkage
Asserts the available library and CRT linkage options for the port.
## Usage
```cmake
vcpkg_check_linkage(
[ONLY_STATIC_LIBRARY | ONLY_DYNAMIC_LIBRARY]
[ONLY_STATIC_CRT | ONLY_DYNAMIC_CRT]
)
```
## Parameters
### ONLY_STATIC_LIBRARY
Indicates that this port can only be built with static library linkage.
### ONLY_DYNAMIC_LIBRARY
Indicates that this port can only be built with dynamic/shared library linkage.
### ONLY_STATIC_CRT
Indicates that this port can only be built with static CRT linkage.
### ONLY_DYNAMIC_CRT
Indicates that this port can only be built with dynamic/shared CRT linkage.
## Notes
This command will either alter the settings for `VCPKG_LIBRARY_LINKAGE` or fail, depending on what was requested by the user versus what the library supports.
